Abstract

The photolysis of some Nfl-dialkylcarbamoyl azides in the presence of carbodiimides gives two types of products cyclic ammonio amates 1 (from Nfl-dialkylamino isocyanates, formed by a photo-Curtius rearrangement of the azides) and five-membered mesoinoic 5- (dialkylamino)-1, 2, 4-triazoles 7, the structure of which was confirmed by independent synthesis. The formation of 7 constitutes a novel reaction path of carbamoyl azides.
