A short synthetic approach to fused 1,2,5-thiadiazoles from the corresponding 1,2,5-oxadiazoles and 1,2,5-selenadiazoles has been developed. Mono- and bis(1,2,5-thiadiazoles) were selectively obtained in high yields. The pathways for these novel reactions were discussed.
已经开发出从相应的1,2,5-恶二唑和1,2,5-硒二唑稠合的1,2,5-噻二唑的短合成方法。高产率选择性地获得了单和双(1,2,5-噻二唑)。讨论了这些新颖反应的途径。
