Reaction of p-tolualdehyde hydrazone with disulfur dichloride in the presence of DBU gave 2,5-di (p-tolyl)-1,3,4-thiadiazole (1a) in 54% yield. Phenyldiazomethane also reacted with disulfur dichloride to afford 2,5-diphenyl-1,3,4-thiadiazole (1b) in 80% yield.
在DBU存在下,对甲苯醛肼与二硫化二氯反应,以54%的产率得到2,5-二(对甲苯基)-1,3,4-噻二唑(1a)。苯基重氮甲烷也与二硫化二氯反应,以80%的产率得到2,5-二苯基-1,3,4-噻二唑(1b)。
