variety of carbonyl compounds have been successfully converted to the corresponding thioacetal derivatives in good to excellent yields on the reaction of carbonyl compounds with 1,2-ethanedithiole, 1,3-propanedithiol, and ethanethiol in the presence of catalytic amount of benzyltriphenylphosphonium tribromide under solvent-free conditions. Some of the major advantages of this method are mild reaction conditions
在催化量的三溴化苄基三苯基鏻存在下,羰基化合物与 1,2-乙二硫醇、1,3-丙二硫醇和乙硫醇的反应已成功地转化为相应的硫代缩醛衍生物无溶剂条件。这种方法的一些主要优点是反应条件温和、效率高以及与其他报道的方法兼容。此外,在这些实验条件下,双键或酮位的 α 位,甚至芳环中都不会发生溴化。
