Abstract

Abstract. 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.

Resumen. Los complejos RhCl(dppe)2, RhCl(dppp)2 y RhCl(dppb)2 donde dppe = difenilfosfino etano; dppp = difenilfosfinopropano;
dppb = difenilfosfinobutano fueron preparados por el tratamiento del RhCl3.3H2O con las fosfinas diterciarias apropiadas. Estos complejos fueron usados como precursores catalíticos en las reacciones de hidrogenación de limoneno, canfeno y 1,5-ciclooctadieno a diferentes concentraciones y temperaturas. Se encontró que el mejor precursor catalítico es el complejo de Rodio con el ligante dppp.
