摘要：

The selective catalytic oxidation of remote primary C-H bonds of organic substrates remains an intellectual and practical challenge. One example of metal-mediated functionalization (hydroxylation) of remote primary C-H bonds in involves the combination of PtCl42-/PtCl62- (the Shilov system). Despite its many attractive features, however, the Shilov system suffers from one crippling drawback:dixoygen cannot be used efficiently as the reoxidant. We have discovered that, with a proper cocatalyst at elevated temperature, Shilov chemistry can be made catalytic in dioxygen. A number of aliphatic acids were tested, and turnover numbers of un to 15/hour were observed.
