| pubmed:abstractText |
[reaction: see text] The catalytic oxidation of the allylic alcohols 1d-n with iodosobenzene diacetate, mediated by the [Cr(III)(salen)]X complex, affords the respective enones in excellent chemoselectivity for Cl(-) as counterion [complex A(Cl)], while for the counterions TfO(-) [complex A(TfO)] and PF(6)(-) [complex A(PF(6)())] nearly equal amounts of enone and epoxide are observed. This counterion-dependent oxidation of allylic alcohols by Cr(III)(salen) complexes is rationalized in terms of Lewis acid catalysis by the complex A(Cl) and redox catalysis for A(TfO) and A(PF(6)()).
