REACTION OF N-(2,2-DIPHENYLVINYLIDENE)ANILINES WITH DICHLOROCARBENE

The reaction of N-(2,2-diphenylvinylidene)anilines with dichlorocarbene, generated by the reaction of chloroform with potassium tert-butoxide, leads to the formation of N-aryl-N-(2,2-diphenylvinyl)carbamoyl chlorides or tert-butyl N-aryl-N-(2,2-diphenylvi

A New Route to Diarylisoquinolones

The lithium salts derived from position 3 of phthalides react with Schiff's bases to form a mixture of cis- and trans-2,3-disubstituted 4-hydroxy-3,4-dihydro-1(2H)-isoquinolones, the former isomer predominating.Acid-catalysed dehydration of the alcohols gives 2,4-disubstituted 1(2H)-isoquinolones, as a result of aryl group migration, whilst the cis-isomers, with methanesulphonyl chloride-pyridine as dehydrating agent, produce the 2,3-disubstituted 1(2H)-isoquinolones.
