Chemo- and stereoselective CH oxidations and epoxidations/cis-dihydroxylations with H2O2, catalyzed by non-heme iron and manganese complexes

An iron catalyst for oxidation of alkyl C-H bonds showing enhanced selectivity for methylenic sites

Many are called but few are chosen: A nonheme iron complex catalyzes the oxidation of alkyl C-H bonds by using H(2)O(2) as the oxidant, showing an enhanced selectivity for secondary over tertiary C-H bonds (see scheme).

Highly efficient, regioselective, and stereospecific oxidation of aliphatic C-H groups with H2O2, catalyzed by aminopyridine manganese complexes

Aminopyridine manganese complexes [LMn(II)(OTf)(2)] having a similar coordination topology catalyze the oxidation of unactivated aliphatic C-H groups with H(2)O(2), demonstrating excellent efficiency (up to TON = 970), site selectivity, and stereospecificity (up to >99%).
