摘要：

The halopentacarbonylmetal compounds of molybdenum and tungsten react with phosphines in polar aprotic solvents with CO substitution to give the ionic derivatives [LM(CO)4X]- (X = Cl, Br; M = Mo, W; L = i-PrnPh3-nP, (Me2N)nPh3-nP, (i-PrO)nPh3-nP, Ph2MeP, Et3P, (PhO)3P, n = 0, 1, 2, 3). The substitution of the halide ligand, which is catalysed by protic solvents, provides a convenient route to the neutral complexes LM(CO)5 and LL′M(CO)4 (L = phosphines; L′ = ammonia, acetonitrile, pyridine, piperidine). cis-(NH3)(i-Pr3P)W(CO)4 in solution is slowly deuterated by D2O. In this reaction all three hydrogen atoms appear to be exchanged simultaneously. © 1979.
