MONTALVO, Liliana; BOLANOS, Alberto  e  CABRERA, Armando. Catalytic Activity of Rhodium (I) Complexes with Bidentate Phosphinic Ligands in the Hydrogenation of Unsaturated Alycyclic Substrates. J. Mex. Chem. Soc [online]. 2007, vol.51, n.1, pp.08-14. ISSN 1870-249X.

RhCl(dppe)₂, RhCl(dppp)₂ and RhCl(dppb)₂ where dppe = diphenylphosphinoethane; dppp = diphenylphosphinopropane; dppb = diphenylphosphinobutane complexes were prepared by treating RhCl₃.3H₂O with the appropriate di(tertiaryphosphine). These complexes were used as catalytic precursors in the hydrogenation of limonene, camphene and 1,5- cyclooctadiene at different concentrations and temperatures. It was found that the Rhodium complex having dppp as ligand was the best catalytic precursor.
