Hydrogenation of tris(triphenylphosphine)chlororhodium(I)
Abstract
The reactivities of RhCI(PPh3)3, RhCl(PPh3)2, and Rh2Cl2(PPh3)4 toward H2, and the contributions of each of these species to the overall rate of hydrogenation of RhCl(PPh3)3 in solution, have been determined; RhCl(PPh3)2 is at least 104 times as reactive as the other two species.
