The mechanisms of protonation and substitution of trans- have been investigated in tetrahydrofuran at I=0.1 mol dm-3(n4>) and 25 deg C.In the presence of acid, HX, loss of phosphine and formation of occurs by a variety of pathways dependent upon the nature of the phosphine.When diphosphine=dppe rapid ring opening of the chelate from trans- allows protonation of the pendant phosphorus atom.Subsequent dissociation of the phosphine ligand, and protonation of the metal, with release of dihydrogen, results in the formation of .When diphosphine=depe a further pathway involving initial protonation of the metal is identifiable.In contrast, substitution of trans- by L=CO, MeCN, or PhCN to yield trans-+ has to await the slow dissociation of halide.
