Abstract

Reactions of RhCl(cod)(THP) (cod = 1,5-cyclooctadiene; THP = P(CH2OH)(3)) with PMePh2 or PCyPh2 (Cy = cyclohexyl) in acetone/MeOH solution under H-2 surprisingly form the complexes cis,mer-Rh(H)Cl-2(PRPh2)(3) (R = Me or Cy); both complexes are characterized by crystallography (the first structures in which the hydride ligands of such dihydrido-chloro-trisphosphine complexes have been located), and by detailed H-1 and P-31 NMR spectroscopy. The key role of the THP in the observed chemistry is discussed. (C) 2007 Elsevier B.V. All rights reserved.
