在对Cr(VI)/Cr(III)体系在相转移催化下对醇类的选择性间接电氧化进行了探讨,发现共醇类能被高产率、选择性地氧化为相应的羰基化合物,而非苄醇类则无此效果的基础上,本文是在此基础上,对分子内含有苄醇羟基和另一个非苄醇羟基的二醇类及肟类化合物进行了选择性电氧化的探讨,结果发现,在本实验条件下,共醇羟基能被选择性地氧化为相应的羰基,而分子内共存的非苄醇羟基几乎不受影响;各种肟类化合物也能有选择地氧化裂解为相应的羰基化合物,而不被深度氧化。

The Cr(VI)/Cr(III) as an indirect redox system to oxidize dihydric alcohols containing both a benzylic and a sated hykroxy group, is studied by means of indirect electrical oxidation under phase transfer catalysis. The experimental results show that it could selectively oxidize the benzylic hydroxy group without affecting the primary or secondary aliphatic hydroxy group. Under the similar conditions, various oximes were also selectively oxidized to the corresponding carbonyl compounds.
