A cobalt(II) complex of a new salen analogue as an oxygenation catalyst of higher activity
Abstract
A cobalt(II) complex of 6,6′-bis(benzoylamino)-2,2′-bipyridine {[Co(babp)]} has been found to take up and activate oxygen and act as a catalyst of higher activity and selectivity than the structurally similar N,N′-di(salicylidene)ethylenediamine complexes in the oxygenation of 2,6-di-t-butyl phenol to 2,6-di-t-butyl-p-benzoquinone.
