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 phosphine complexes of ruthenium(II)arenes

Chiral, arene-containing complexes of ruthenium(II) based on the phosphines chiraphos and diop are reported, as well as improved routes to some known analogues containing binap or the achiral phosphines Ph2P(CH2)nPPh2 (n=2, dppe; n=4, dppb).
