Ei-ichi Negishi
was a Japanese chemist who was best known for his discovery of the Negishi coupling. He spent most of his career at Purdue University in the United States, where he was the Herbert C. Brown Distinguished Professor and the director of the Negishi-Brown Institute. He was awarded the 2010 Nobel Prize in Chemistry "for palladium catalyzed cross couplings in organic synthesis" jointly with Richard F. Heck and Akira Suzuki.Press releaseGreat art in a test tube Royal Swedish Academy of Sciences. Accessed October 6, 2010. Early life and education Negishi was born in Hsinking (today known as Changchun), the capital of Manchukuo, in July 1935. Following the transfer of his father who worked at the South Manchuria Railway in 1936, he moved to Harbin, and lived eight years there. In 1943, when he was nine, the Negishi family moved to Incheon, and a year later to Kyongsong Prefecture (now Seoul), both in Japanese-occupied Korea. In November 1945, three months after World War II ended, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hsinking
Changchun (, ; ), also romanized as Ch'angch'un, is the capital and largest city of Jilin Province, People's Republic of China. Lying in the center of the Songliao Plain, Changchun is administered as a , comprising 7 districts, 1 county and 3 county-level cities. According to the 2020 census of China, Changchun had a total population of 9,066,906 under its jurisdiction. The city's metro area, comprising 5 districts and 1 development area, had a population of 5,019,477 in 2020, as the Shuangyang and Jiutai districts are not urbanized yet.

Palladium-catalyzed Coupling Reactions
In organic chemistry, a cross-coupling reaction is a reaction where two fragments are joined together with the aid of a metal catalyst. In one important reaction type, a main group organometallic compound of the type R-M (R = organic fragment, M = main group center) reacts with an organic halide of the type R'-X with formation of a new carbon–carbon bond in the product R-R'. Cross-coupling reaction are a subset of coupling reactions. It is often used in arylations. Richard F. Heck, Ei-ichi Negishi, and Akira Suzuki were awarded the 2010 Nobel Prize in Chemistry for developing palladium-catalyzed coupling reactions. Mechanism The mechanism generally involves reductive elimination of the organic substituents R and R' on a metal complex of the type LnMR(R') (where L is some arbitrary spectator ligand). The crucial intermediate LnMR(R') is formed in a two step process from a low valence precursor Ln. The oxidative addition of an organic halide (RX) to LnM gives LnMR(X). Subseq ...

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Korea Under Japanese Rule
Between 1910 and 1945, Korea was ruled as a part of the Empire of Japan. Joseon Korea had come into the Japanese sphere of influence with the Japan–Korea Treaty of 1876; a complex coalition of the Meiji government, military, and business officials began a process of integrating Korea's politics and economy with Japan. The Korean Empire, proclaimed in 1897, became a protectorate of Japan with the Japan–Korea Treaty of 1905; thereafter Japan ruled the country indirectly through the Japanese Resident-General of Korea. Japan formally annexed the Korean Empire with the Japan–Korea Treaty of 1910, without the consent of the former Korean Emperor Gojong, the regent of the Emperor Sunjong. Upon its annexation, Japan declared that Korea would henceforth be officially named Chōsen. This name was recognized internationally until the end of Japanese colonial rule. The territory was administered by the Governor-General of Chōsen based in Keijō (Seoul). Japanese rule prioritized ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gyeonggi Province
Gyeonggi-do (, ) is the most populous province in South Korea. Its name, ''Gyeonggi'', means "京 (the capital) and 畿 (the surrounding area)". Thus, ''Gyeonggi-do'' can be translated as "Seoul and the surrounding areas of Seoul". Seoul, the nation's largest city and capital, is in the heart of the area but has been separately administered as a provincial-level ''special city'' since 1946. Incheon, the nation's third-largest city, is on the coast of the province and has been similarly administered as a provincial-level ''metropolitan city'' since 1981. The three jurisdictions are collectively referred to as '' Sudogwon'' and cover , with a combined population of 25.5 million—amounting to over half of the entire population of South Korea. History Gyeonggi-do has been a politically important area since 18 BCE, when Korea was divided into three nations during the Three Kingdoms period. Ever since King Onjo, the founder of Baekje (one of the three kingdoms), founded the govern ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Incheon
Incheon (; ; or Inch'ŏn; literally "kind river"), formerly Jemulpo or Chemulp'o (제물포) until the period after 1910, officially the Incheon Metropolitan City (인천광역시, 仁川廣域市), is a city located in northwestern South Korea, bordering Seoul and Gyeonggi to the east. Inhabited since the Neolithic, Incheon was home to just 4,700 people when it became an international port in 1883. Today, about 3 million people live in the city, making it South Korea's third-most-populous city after Seoul and Busan. The city's growth has been assured in modern times with the development of its port due to its natural advantages as a coastal city and its proximity to the South Korean capital. It is part of the Seoul Capital Area, along with Seoul itself and Gyeonggi Province, forming the world's fourth-largest metropolitan area by population. Incheon has since led the economic development of South Korea by opening its port to the outside world, ushering in the modernization o ...

The Nikkei
''The Nikkei'', also known as , is the flagship publication of Nikkei, Inc. (based in Tokyo) and the world's largest financial newspaper, with a daily circulation exceeding 1.73 million copies. The Nikkei 225, a stock market index for the Tokyo Stock Exchange, has been calculated by the newspaper since 1950. It is one of the four national newspapers in Japan; the other three are ''The Asahi Shimbun'', the ''Yomiuri Shimbun'' and the ''Mainichi Shimbun''. History The roots of the Nikkei started with an in-house newspaper department of Mitsui & Company in 1876 when it started publication of ''Chugai Bukka Shimpo'' (literally ''Domestic and Foreign Commodity Price Newspaper''), a weekly market-quotation bulletin. The department was spun out as the ''Shokyosha'' in 1882. The paper became daily (except Sunday) in 1885 and was renamed ''Chugai Shōgyō Shimpo'' in 1889. It was merged with ''Nikkan Kōgyō'' and ''Keizai Jiji'' and renamed ''Nihon Sangyō Keizai Shimbun'' in 1942. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

South Manchuria Railway
The South Manchuria Railway ( ja, 南満州鉄道, translit=Minamimanshū Tetsudō; ), officially , Mantetsu ( ja, 満鉄, translit=Mantetsu) or Mantie () for short, was a large of the Empire of Japan whose primary function was the operation of railways on the Dalian– Fengtian (Mukden)–Changchun (called Xinjing from 1931 to 1945) corridor in northeastern China, as well as on several branch lines. In 1905, after Russia's defeat in the Russo-Japanese War, this area was taken over by Japan as the South Manchuria Railway Zone. Mantetsu was established in 1906 to operate the railways taken over from the Russians. Subsequently, Mantetsu expanded by building new lines for itself and for Chinese-owned undertakings, and after the establishment of the puppet state of Manchukuo in 1932, it was also entrusted with the management of the Manchukuo National Railway. Between 1917 and 1925, Mantetsu was also responsible for the management of the Chosen Government Railway in Japanese-oc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
