'Grignard-analogous' rhodium phosphane complexes

Interesting stoichiometric and catalytic reactions are possible with the rhodium phosphane complexes [{Ph2P(CH2)(n)PPh2)(n)}2Rh][MgC1] (1: a, n = 2; b, n = 3), which are readily accessible by reaction of the chloride complexes 2 with active magnesium. The 'Grignard-analogous' compounds 1 react to form 3 (E = H, Me SiMe3) by protolysis, alkylation, and silylation. The interconversion of complexes 2a and 1a can be used for catalytic transfer of two electrons from magnesium to CO2 to yield CO and CO3/2+.

MONO- AND DINUCLEAR RHODIUM CARBONYL SPECIES CONTAINING MONODENTATE OR BRIDGING 1,3-BIS(DIPHENYLPHOSPHINO)PROPANE

The interaction of 2(μ-CO)2 with H2 in CH2Cl2 in the presence of varying amounts of dpp leads mainly to catalytically important species which include Rh(H)CO)(dpp)(dpp*) and 2(μ-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 a non-detected RhH(CO)(dpp) species are suggested.
