The reaction of phosphino- and arsino-ketene complexes of tungsten η5-C5H5(CO[P(CH3)3] XW[η1-R2Y(C6H4CH3)CCO] (X = Cl, I; Y = P, As) with trialkylphosphines does not lead to a substitution of the phosphino- and arsinoketene ligands but to a nucleophilic attack of the phosphine at the central ketene carbon and a concomitant substitution of the halogene ligand via the former ketene oxygen, affording
