Abstract

The interaction of [Rh(CO)(dpp)]2(mu-CO)2 with H-2 in CH2Cl2 in the presence of varying amounts of dpp leads mainly to catalytically important species which include Rh(H)(CO)(dpp)(dpp*) and [RhH(CO)(dpp)]2(mu-dpp), these being formed also by treating RhH(dpp)2 with about 2 equivalents of CO; dpp and dpp* = bidentate and monodentate 1,3-bis(diphenylphosphino)propane, respectively. Mechanistic pathways involving a detected RhH(CO)2(dpp) and non-detected <> species are suggested.
