Abstract

Abstract The new P-donor ligands PPh 3–n (OC 9 H 19) n (n= 3, 2, 1) containing branched alkyl chains were synthesised and their coordination to Rh I and Pd II studied. The X-ray structure of [Rh {PPh 2 (OC 9 H 19)} 4] PF 6 was determined. Reaction of the [Rh (acac)(CO) 2]/PPh 3–n (OC 9 H 19) n systems with CO/H 2 at 5 atm and 80 C in toluene led to the formation of [RhH (CO){PPh 3–n (OC 9 H 19) n} 3] as the main species. The Rh-catalysed ...
