Abstract

Abstract Azidobenzothiazole and azidobenzimidazole and certain of its derivatives react with triphenyl-phosphine to give isolatable adducts which decompose thermally to give the corresponding phosphinimines. 2-Azidobenzoxazole gives an adduct which loses nitrogen at 15–20 and gives the phosphinimine directly. Methylation of the phosphinimines occurs at the hetero nitrogen, whereas benzoylation occurs at the exo nitrogen atom. The structures ...
