OsO₄ in Ionic Liquid [Bmim]PF₆: A Recyclable and Reusable Catalyst System for Olefin Dihydroxylation. Remarkable Effect of DMAP

Abstract

[reaction: see text] The combination of the ionic liquid [bmim]PF(6) and DMAP provides a most simple and practical approach to the immobilization of OsO(4) as catalyst for olefin dihydroxylation. Both the catalyst and the ionic liquid can be repeatedly recycled and reused in the dihydroxylation of a variety of olefins with only a very slight drop in catalyst activity.
