Salen)Mn(III) catalysts show increased turnover numbers in the catalytic asymmetric epoxidation of conjugated olefins upon addition of bulky Lewis acids (LA) such as zinc tetraphenylporphyrin (ZnTPP). Up to 3-fold increase in total catalytic activity and at least a 20-fold increase in catalyst stabi
A polymerizable unsymmetric tetradentate Schiff base with one vinyl group 3 was synthesized and copolymerized with styrene in toluene. Mn(III) ion was quantitatively incorporated into the copolymers by the functional moieties. The resulting linear polymer-bound manganese complexes ( 4a and 4b) were
