Platinum–triethylamine-catalyzed hydrogenation of aldehydes and cyclohexanones
摘要:
The first hydrogenation of aldehydes and chemoselective hydrogenation of cyclohexanones catalyzed by PtO2-Et3N are presented. An additionally attractive feature of this hydrogenation is being applicable to the complicated molecules. Three equivalent of triethylamine and 0.05 equiv Of PtO2 in 95% ethanol are found to be the optimal condition. (c) 2009 Elsevier Ltd. All rights reserved.
