Abstract

Abstract: Epoxides have been obtained from aldehydes and phenyldiazomethane using catalytic amounts of both the copper homoscorpionate complexes TpxCuL (Tpx= homoscorpionate ligand; L= acetonitrile or tetrahydrofuran, THF) and dimethyl sulfide (SMe2) in high yields and diasteroselectivities, and with activities higher (TOF= 46 hÀ1) than those already known with rhodium-or copper-based catalysts. Among the copper (I) ...
