Reaction of N'-phenylthioformohydrazide with carbonyl compounds, such as aliphatic, aromatic and heterocyclic aldehydes and a ketone, in the presence of trimethylsilyl chloride proceeded easily to afford the corresponding 2, 2'-substituted-2, 3-dihydro-3-phenyl-1, 3, 4-thiadiazoles in good yields under mild conditions.
在三甲基氯硅烷存在下,N'-苯硫基甲酰肼与羰基化合物(如脂肪族、芳香族和杂环醛以及酮)的反应很容易进行,在温和的条件下以良好的收率得到相应的 2,2'-取代-2,3-二氢-3-苯基-1,3,4-噻二唑。
