Sulphinyl-controlled formation of diastereoisomerically pure (oxadiene)tricarbonyliron(0) complexes
Abstract
The sulphonyl and sulphinyl substituted oxadienes [RS(O)nCHCHC(Me)O; R = But, Ph; n= 2,1] form stable tricarbonyliron(0) complexes; the sulphinyl complexes formed are diastereoisomerically pure and the relative stereochemistry of the tricarbonyliron(0) unit and the sulphinyl substituent in the products has been determined by an X-ray crystal structure analysis of [ButS(O)CHCHC(Me)O](CO)3Fe0.
