Abstract

Reactions of Trichloroacetyl Isothiocyanate with Organic Azides. -13C NMR spectroscopic investigations of the title reactions in chloroform and acetone reveal the formation of 1,2,4-oxathiazolidines, which cannot be isolated. They decompose via carbodiimide intermediates into the products (III). Some trapping experiments with ( IV) and (VI) yield the compounds (V) and (VII), respectively. Reaction mechanisms are presented. -(L'ABBE, G.; BOSMAN, J.; TOPPET, S.; J. Heterocycl. Chem. 29 (1992) 1, 17-23; Dep. Chem., Univ. Leuven, 3001 Leuven, Belg.; EN)
