The smooth and neutral acylation of amines to form amides by photoactivation of N-acyl-5,7-dinitroindolines is described. An improved acylation of nitroindolines allows the convenient preparation of N-acylnitroindolines. This reaction makes possible the recycling of the nitroindoline released during the photoactivation.

A study of esteraminolysis in the presence of dodecylammonium carboxylatereversedmicelles showed that the catalytic role of the surfactant head-anion (general base) was concentration independent. The presence of cosolubilized water in the micelle did not lead to detectable ester hydrolysis.
