Acceptorless and Base-free Dehydrogenation of Cyanohydrin with (η6-Arene)halide(Bidentate Phosphine)ruthenium(II) Complex

Ruthenium-catalyzed dehydrogenation of cyanohydrins under acceptorless and base-free conditions was demonstrated for the first time in the synthesis of acyl cyanide. As opposed to the thermodynamically preferred elimination of hydrogen cyanide, the dehydrogenation of cyanohydrins could be kinetically controlled with ruthenium (II) bidentate phosphine complexes. The effects of the arene, phosphine ligands and counter anions were investigated in regard to catalytic activity and selectivity. Selective dehydrogenation can occur via β-hydride elimination with the experimentally observed [(alkoxide)Ru] complex. (Figure presented.).

Chiral Induction in Photochemical Reactions, XIII The Paterno-Buechi Reaction of Achiral and Chiral Acyl Cyanides with Furan

The acyl cyanides 1a-d are prepared from the corresponding acyl chlorides.The Paterno-Buechi reaction of 1a-f with furan (2) yields the bicyclic oxetanes 3a-f with an endo/exo ratio varying from 3.5:1 (1a) to 16:1 (1d).However, in the reaction of the chiral acyl cyanides 1b and 1c, a low chiral induction is observed (maximum de: 13 percent).
