picture info	Hiyama Subprefecture is a subprefecture of Hokkaido Prefecture, Japan located on the Oshima Peninsula on the Sea of Japan side. It includes Okushiri Island. It was established in 1897. Geography Mergers History 1897: Hiyama Subprefecture was established. 2005: Kumaishi Town ( Nishi District) was merged with Yakumo Town ( Yamakoshi District, Oshima Subprefecture) and transferred to Oshima Subprefecture. At the same time, Hiyama Subprefecture was divided between north and south. 2014: Esashi Line (from Kikonai Station to Esashi Station was a railway station on the Esashi Line in Esashi, Hokkaido, Japan, operated by Hokkaido Railway Company (JR Hokkaido). It opened in 1936 and closed in May 2014. Lines Esashi Station was formerly the terminus of the non-electrified section of ...) was abolished. Therefore, Hiyama Subprefecture became the only subprefecture in which there is no railway. External links Official Website {{Hokkaido-geo-stub Subprefectures in Hokkaido ...

picture info	Hiyama Coupling The Hiyama coupling is a palladium-catalyzed cross-coupling reaction of organosilanes with organic halides used in organic chemistry to form carbon–carbon bonds (C-C bonds). This reaction was discovered in 1988 by Tamejiro Hiyama and Yasuo Hatanaka as a method to form carbon-carbon bonds synthetically with chemo- and regioselectivity. The Hiyama coupling has been applied to the synthesis of various natural products. :\begin\\ \ce \end :* R: aryl, alkenyl or alkynyl :* R': aryl, alkenyl, alkynyl or alkyl :* R'': Cl, F or alkyl :* X: Cl, Br, I or OTf Reaction history The Hiyama coupling was developed to combat the issues associated with other organometallic reagents. The initial reactivity of organosilicon was not actually first reported by Hiyama, as Kumada reported a coupling reaction using organofluorosilicates shown below. Organosilanes were then discovered, by Hiyama, to have reactivity when activated by a fluoride source. This reactivity, when combined with a palladium s ...
