WebJan 1, 2006 · Robert Pschorr (1868–1930), born in Munich He became an assistant professor in 1899 at Berlin where he discovered the phenanthrene synthesis. During WWI, … WebSuccessful Pschorr cyclization (Method B) implies an azaphilic addition of the transient aryl radical to the [1,2,4]triazine and suggests that other processes involving aryl radicals, 33e.g. transformations of aryl halides in the presence of R 3 SnH 34,35 or R 3 SiH, 36,37 could also lead to N -cyclization and formation of the planar radical. The Pschorr cyclization is a name reaction in organic chemistry, which was named after its discoverer, the German chemist Robert Pschorr (1868-1930). It describes the intramolecular substitution of aromatic compounds via aryldiazonium salts as intermediates and is catalyzed by copper. The reaction is a … See more In the course of the Pschorr cyclization, a diazotization of the starting compound occurs, so that an aryldiazonium salt is formed as intermediate. For this, sodium nitrite is added to hydrochloric acid to obtain See more The Pschorr cyclization has a relatively good atom economy, since essentially only nitrogen is produced as a waste material. For the diazotization, two equivalents of nitrous acid are … See more father\u0027s day inspirational message
