Transfer hydrogenation and transfer hydrogenolysis. V. Hydrogen transfer from amines, ethers, alcohols, and hydroaromatic compounds to olefins catalyzed by chlorotris(triphenylphosphine)rhodium(I)

Transfer Hydrogenation Including the Meerwein‐Ponndorf‐Verley Reduction

“…With piperidine as hydrogen donor, the highly reactive 1-piperidene intermediate undergoes trimerization or, in the presence of amines, an addition reaction [77]. Pyridine was not observed as a reaction product.…”

Hydrogen transfer from cyclohexanol to aromatic aldehydes catalyzed by heterogenized ruthenium(II) complexes bound to swellable polymer matrices

“…Based on the results described earlier and a comparison with the mechanism of the transfer hydrogenation from organic compounds to olefins, aldehydes and ketones catalyzed by small molecules of RuH 2 (PPh 3 ) 4 and RhCl(PPh 3 ) 3 [11][12][13][14][15]5], Scheme 3 is reasonably proposed for the catalytic cycle of the hydrogen transfer reaction from cyclohexanol to the aromatic aldehydes catalyzed by the supported heterogeneous catalyst. Here, P-RuHP 3 stands for the CCPAARu catalyst.…”

Kinetic study of hydrogen transfer from benzyl alcohol to aliphatic aldehydes catalysed by heterogenised ruthenium(II) catalysts

“…Based on the results described earlier and on a comparison with the mechanism of transfer hydrogenation of olefins (Imai et al, 1974;Nishiguchi and Fukuzumi, 1974;Nishiguchi et al, 1975), Scheme 2 was reasonably proposed for the catalytic cycle of hydrogen transfer reduction of aldehyde.…”
