A new bifunctional catalyst for tandem Heck–asymmetric dihydroxylation of olefins

Abstract

A new bifunctional catalyst consisting of active palladium and osmium species anchored on silica gel through a mercaptopropyl spacer and a cinchona alkaloid respectively has been prepared for the first time and used in the heterogeneous tandem Heck–asymmetric dihydroxylation of olefins to afford diols with excellent yields and enantiomeric excesses (ee’s) in presence of N-methylmorpholine N-oxide or K3Fe(CN)6 as cooxidants.
