摘要：

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-l, 3, 4-oxadiazoles (6) and 2-amino-l, 3, 4-oxadiazoles (3). respectively. © 1991 Taylor & Francis Group, LLC.
