Abstract

Chiral base-mediated asymmetric functionalisation of tricarbonylchromium(0) complexes of benzyl sulfides gives, after crystallisation, products of high enantiomeric purity (92–99% ee) in acceptable yield (51–76%); an intriguing reversal of stereoselectivity with respect to the analogous oxygen systems is noted.
