A mild and efficient rhenium-catalyzed transfer hydrogenation of terminal olefins using alcoholysis of amine-borane adducts as a reducing system

Abstract

ReBr(2)(NO)(CH(3)CN)(PTA)(2)] (PTA - 1, 3, 5-triaza-7-phosphaadamantane) catalyzes the alcoholysis of ammonia-borane and amine-boranes and the catalytic transfer hydrogenations of various terminal olefins. Excellent yields were achieved at 70 degrees C in isopropanol using tBuOK as a co-catalyst affording TOF values up to 396 h(-1). (C) 2011 Elsevier B.V. All rights reserved
