Article abstract of DOI:10.1039/DT9870002969

The novel preparation of a wide variety of trans-2> complexes (X = anionic ligand, L = tertiary phosphine) from , phosphine (L), and acid (HX) is described.A plausible formation pathway is proposed.The electron density on the phosphorous atom in trans-2> decreases and the length of the Rh-P bond increases with an increase in the electronegativity of the anionic ligand, X, in a cis position to the phosphine ligand.The rhodium complexes (X = arylcarboxylate) are reduced to afford rhodate anions such as - and - in hexamethylphosphoroamide solution under CO-H2.The rate of reduction increases with a decrease in the electron-withdrawing effect of the arylcarboxylate ligand.
