Abstract

The epoxidation of olefins with methyltrioxorhenium (MTO) in the presence of various chiral oxazolines and pyridinebis(oxazoline) ligands as well as achiral N-ligands has been investigated. By applying 1-octene as a model system, reaction conditions were optimized, and high yields and good chemoselectivity (>90 %) were achieved. By applying other aromatic and aliphatic olefins, similar chemoselectivities and up to 19 % enantioselectivity were obtained. The epoxidation of 1-octene using methyltrioxorhenium (MTO) in the presence of pyridinebis(oxazoline) and related ligands is reported. Although excellent chemoselectivity (>90 %) and good yields were obtained, low enantioselectivity was observed.
