The aza-Wittig reaction of N-acylamino iminotriphenylphosphoranes with carbon disulfide, isocyanates and isothiocyanates, lead to the very reactive heterocumulenic systems (5) and (2) which undergo spontaneous cyclization to 5-substituted 2-mercapto-1,3,4-oxadiazoles (6) and 2-amino-1,3,4-oxadiazoles (3), respectively.
