Hydrogenation 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.

Abstract

Hydrogenation 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.
