Fast, efficient, and highly stereoselective epoxidation with H 2O2 is reached by manganese coordination complexes with e-rich aminopyridine tetradentate ligands. It is shown that the electronic properties of these catalysts vary systematically with the stereoselectivity of the O-atom transfer event and exert fine control over the activation of hydrogen peroxide, reducing the amount of carboxylic acid co-catalyst necessary for efficient operation.

Stereoselective 7α-hydroxylation reaction of Δ5-steroids by a Fe(PA; picolinate)3/H2O2/MeCN system is presented. The 7α-hydroxylation reactions were achieved in 33-40% yields by addition of 30%-H2O2 to a solution of 3β-acetoxy-Δ5-steroids 1a-1d and a crystalline of Fe(PA)3 in MeCN.
Benzotriazole-Chromium Trioxide Complex a Versatile Oxidant of Organic Compounds
Parish, Edward J.,Honda, Hiroshi,Hileman, Deborah L.
, p. 3359 - 3366 (2007/10/02)
Benzotriazole has been found to complex with chromium trioxide to produce a versatile new oxidant.This complex is capable of oxidizing primary alcohols to carboxylic acids, secondary alcohols to ketones, and bringing about the allylic oxidation of olefin substrates.
