苄基三苯基高碘酸季鏻盐的合成其及氧化性能研究

The Synthesis and Oxidization of Benzyltriphenylphosphonium Periodate

用苄基三苯基氯化钅米舛 与高碘酸根反应制备稳定的苄基三苯基高碘酸盐氧化剂 ,在非质子溶剂中和 L ewis酸催化下 ,有效地氧化伯醇为醛、仲醇为酮、苯硫酚为二苯二硫化合物 ,产率 5 6 %～ 95 % ,探讨了不同的反应溶剂及 L ewis酸对该反应的影响。

Benzyltriphenylphosphonium periodate was prepared by the reaction of benzyltriphenylphosphonium chloride with periodate. It was a stable oxidizer and can efficiently oxidize primary alcohols to aldehydes, secondary alcohols to ketones, thoils to disulfide in acetonitrile in the presence of aluminium chloride with the yields of 56%~95%. The effect of solvent and lewis acid on the reaction was also discussed.$$$$
