Asymmetric epoxidation catalysed by an iron ‘binap capped’ porphyrin
Abstract
A new chiral metalloporphyrin (iron ‘binap capped’ porphyrin) has been synthesized and used to catalyse the asymmetric epoxidation of various unsubstituted aromatic olefins; [binap = 2,2′-bis(diphenylphosphino)-1,1′-binaphthyl].
