Activation of H2 with allylpalladium(II) derivatives. Selective catalytic hydrogenation of allene to propene
No full textThe behaviour of allylpalladium(II) complexes in THF towards molecular hydrogen under mild experimental conditions has been studied. The decomposition to palladium metal and propane is discussed in terms of the fluxionality of the allyl moiety and the stability of a proposed PdH intermediate. Reaction of allylpalladium(II) complexes with H2 and allene results in catalytic selective hydrogenation to give propene. © 1978
Atomically dispersed Palladium as a borderline case between heterogeneous and homogeneous hydrogenation of olefins
No full textSelective hydrogenation of dienes to monoenes catalyzed by allyl-Pd(II) complexes
No full textHydrogenation of 1,5-COD, 1,3-COD, 1,4-octadiene and 1,7-octadiene to the corresponding monoenes has been carried out under mild conditions, using different (allyl)Pd(II) derivatives in N,N-dimethylacetamide solution. Experiments on the 1,3-COD system suggest a mechanism involving the formation of hydrido-Pd(II) species followed by insertion of diene to restore the allylic moiety. Non conjugated dienes are isomerized prior to hydrogenation. The complete selectivity appears to result from an intrinsic property due to formation of η3-allylic intermediates. © 1979
