RuCl2[S-BINAP]-catalyzed synthesis of aldehydes and ketones by dehydrogenation of alcohols

Autor: Jef A. J. M. Vekemans, G.B.W.L. Ligthart, J Jan Meuldijk, R. H. Meijer, L.A. Hulshof

Publikováno v: Journal of Molecular Catalysis A: Chemical, 218(1), 29-40. Elsevier

RuCl 2 [ 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

Highly sustainable catalytic dehydrogenation of alcohols with evolution of hydrogen gas

Autor: M. P. J. Donners, L.A. Hulshof, G.B.W.L. Ligthart, J Jan Meuldijk, Jef A. J. M. Vekemans, R. H. Meijer

Publikováno v: Tetrahedron Letters, 44(7), 1507-1509. Elsevier

The catalytic dehydrogenation of alcohols into aldehydes and ketones in the absence of H-acceptors was studied with several transition metal catalysts in order to develop a large-scale procedure. Applying Ru(OCOCF3)2(CO)(PPh3)2, the so called Robinso

Triruthenium dodecacarbonyl/triphenylphosphine catalyzed dehydrogenation of primary and secondary alcohols

Autor: Huub Kooijman, G.B.W.L. Ligthart, L.A. Hulshof, J Jan Meuldijk, Allison M. Mills, R. H. Meijer, Anthony L. Spek, Jef A. J. M. Vekemans

Publikováno v: Tetrahedron, 60(5), 1065-1072. Elsevier

Dehydrogenation of alcs. into aldehydes and ketones by Ru3(CO)12/PPh3 based homogeneous catalysis has been investigated as an alternative for the classical Oppenauer oxidn. Several catalytic systems have been screened in the Oppenauer-like oxidn. of
