HYDRORUTHENATION OF PROP-2-YNYLTRIPHENYLPHOSPHONIUM BROMIDE - SYNTHESIS, CRYSTAL-STRUCTURE AND REACTIONS OF [RUBR(CH=CHCH(2)PPH(3))(CO)(PPH(3))(2)]PF6

The reaction of the complex [RuClH(CO)(PPh(3))(3)] with prop-2-ynyltriphenylphosphonium bromide ([Ph(3)PCH(2)C equivalent to CH]Br) followed by NH4PF6 provides the crystallographically characterised salt [RuBr(CH=CHCH(2)PPh(3))(CO)(PPh(3))(2)]PF6 which by virtue of the coordinative unsaturation at the ruthenium centre undergoes addition of the ligands CNC(6)H(3)Me(2)-2,6, and CO to Ru and insertion of SO2 into the Ru-C sigma-bond.
