Abstract
A number of unfunctionalized aromatic and aliphatic olefins was tested in ruthenium-catalyzed epoxidation with tert-butyl hydroperoxide as t he external oxidant. The effect of reaction without ligands and with t wo different type of ligands was investigated. Olefins containing term inal double bonds afforded low epoxide selectivities, whereas secondar y and tertiary olefins afforded up to 80% selectivity for the epoxide. A mechanism for the ruthenium-catalyzed epoxidation with tert-butyl h ydroperoxide is proposed. Copyright (C) 1996 Elsevier Science Ltd
