Pictet–Spengler Reaction
The Pictet–Spengler reaction is a chemical reaction in which a β-arylethylamine undergoes condensation with an aldehyde or ketone followed by ring closure. The reaction was first discovered in 1911 by Amé Pictet and Theodor Spengler (February 22, 1886 - August 18, 1965). Traditionally an acidic catalyst in protic solvent was employed with heating, however the reaction has been shown to work in aprotic media in superior yields and sometimes without acid catalysis. The Pictet–Spengler reaction can be considered a special case of the Mannich reaction, which follows a similar reaction pathway. The driving force for this reaction is the electrophilicity of the iminium ion generated from the condensation of the aldehyde and amine under acid conditions. This explains the need for an acid catalyst in most cases, as the imine is not electrophilic enough for ring closure but the iminium ion is capable of undergoing the reaction. The Pictet-Spengler reaction is widespread in both ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marc-Auguste Pictet
Marc-Auguste Pictet (; 23 July 1752 – 19 April 1825) was a Swiss scientific journalist and experimental natural philosopher.

Adolphe Pictet
Adolphe Pictet (11 September 1799 – 20 December 1875) was a Swiss linguist, philologist and ethnologist. Pictet, the cousin of the biologist Francois Jules Pictet, is well known for his research in the field of comparative linguistics. He played a crucial formative role in the development of Ferdinand de Saussure; "it was Pictet who introduced the thirteen-year-old Saussure to the theoretical foundations of Indo-European linguistics." But he was also "a dedicated champion of German Romanticism and idealist philosophy":Like French, English, and Russian Romantics since the beginning of the century, he made a journey to Germany, where he became acquainted with A. W. Schlegel (with whom he maintained an important correspondence over the course of many years), Goethe, Hegel, Schleiermacher, and Schelling. ... In the spirit of earlier wars between “romantics” and “classics” (a little outmoded by the 1850s), Pictet envisioned Romanticism, with its embrace of pluralism and ...

Raoul Pictet
Raoul-Pierre Pictet (4 April 1846 – 27 July 1929) was a Swiss physicist. Pictet is co-credited with French scientist Louis-Paul Cailletet as the first to produce liquid oxygen in 1877. Biography Pictet was born in Geneva. He served as professor in the university of that city. He devoted himself largely to problems involving the production of low temperatures and the liquefaction and solidification of gases.For biographical details, see On December 22, 1877, the Academy of Sciences in Paris received a telegram from Pictet in Geneva reading as follows: ''Oxygen liquefied to-day under 320 atmospheres and 140 degrees of cold by combined use of sulfurous and carbonic acid.'' This announcement was almost simultaneous with that of Cailletet who had liquefied oxygen by a completely different process. Pictet died in Paris in 1929.

Pictet (crater)
Pictet is a lunar impact crater located just to the east of the larger and more prominent impact crater Tycho. The high-albedo rays and ejecta from Tycho lie across Pictet and spread far to the east and in other directions. Pictet is older than Tycho and is somewhat worn by past impacts. The slightly smaller crater Pictet A intrudes slightly into the southwest rim. The larger crater Pictet E is nearly joined to the north rim. To the east is Saussure, and to the northeast is the larger, worn formation Orontius. Swiss physicist Marc-Auguste Pictet Marc-Auguste Pictet (; 23 July 1752 – 19 April 1825) was a Swiss scientific journalist and experimental natural philosopher.
