RuCl2[S-BINAP]-catalyzed synthesis of aldehydes and ketones by dehydrogenation of alcohols
RuCl2[S-BINAP] catalyzed dehydrogenation of alcohols into aldehydes or ketones has been investigated. Among many H-acceptors screened, diphenylacetylene (tolane) was the most suitable judged from its smooth reduction. Electron rich and deficient analogues of tolane have been synthesized. Based on competition experiments between these H-acceptors a tentative catalytic cycle for the RuCl2[S-BINAP] catalyzed dehydrogenations is proposed. (C) 2004 Elsevier B.V. All rights reserved.
