Imide bond formation, synthetic

Benzylideneanilines have been added across 2,3-dihydrofurans to produce bicyclic azetidines regio- and stereoselectively a zwitterionic mechanism is proposed. An extensive range of reaction parameters have been calculated for the Mannich reaction of benzoxazole with formaldehyde/dimethylamine. A molybdenum bis(imide) has been used to catalyse C=N bond formation in imine-imine metathesis reactions of synthetic interest the approach has been extended to alkylidene-imine, imide-imine, and imide-imide metatheses. 1-Substituted 1-phenyl-... 

Irradiation at 254 nm of the imidate (Scheme 2) in aqueous solutions results in the formation of 4-cyanophenol and A -isopropylbenzamide. The photochemical step involved in the formation of the products has been shown to be C-O bond fission with the production of the phenoxide and the benzonitrilium ion. Mariano and co-workers have reported a detailed study of the electron-transfer photochemistry of a-anilino carboxylates, p-anilinoalcohols and a-an-ilinosilanes. This study has measured the rates of decarboxylation of aniliniumcarboxylate radicals. The base induced retro-Aldol fragmentations of the radical-cations formed from the p-anilinoalcohols and the influence of substituents on the nitrogen on the desilylation of the a-anilinosilanes was also investigated. In addition, the synthetic potential of some of the electron-transfer photochemistry of the carboxylate salts (181) and (182) has been examined. In these examples irradiation, using DCA in methanol or acetoni-...
