Phenols thioacylation

Thioacylation of Alcohols and Phenols with Thioacyl Halides... [Pg.435]

The thioacyl-arylhydrazides (187 R = Me, Et, Pr, or Ph) react with phosphorus oxychloride to yield the iminium salts (189) by way of the suggested intermediates (188). Quantum yields for the photocyclization (190) (191) (R = H, Bu, Ph, OMe, NO2, etc ) have been determined.Oxidation of the phenolic amino-ester (192), i.e. a dopachrome reaction, gives the quinone imine...
