摘要：
A new method for the synthesis of azolo[5,1-c]-1,2,4-triazine ring systems is reported by the sequential formation of triazine ring based on the regioselective formation of the azophosphoranes from hydrazonyl chlorides, followed by the intermolecular Wittig reaction with carboxylic acid chlorides, phenylisocyanate, and carbon disulfide.
