摘要：

In acetonitrile the bis(pyridine)cobalt(II) complex [Co(II)(bpy)2](ClO4)2] activates dioxygen via the reversible formation of a mu-dioxygen complex. This complex dehydrogenates (oxidizes) N-methylanilines, benzyl alcohol, and aldehydes (with subsequent autoxidation). In the absence of substrate, the Co(II)(bPy)2(2+) complex reduces dioxygen via residual water in the solvent to generate HOOH. The complex does not activate O2 for reaction with hydrocarbons [even 1,4-cyclohexadiene (DELTA-H(DBE) 73 kcal mol-1) is inert].
