Reaction of the chloromethylchlorophosphines R(Cl)P-CH2-Cl (R = Cl, tBu, C6H11, NEt2, NPh2) (L) with C7H8Mo(CO)4 or (CO)5W(Py), (CO)6W and (CO)5W(THF) yields the complexes cis-Mo(CO)4L2(2a - 2e) or (CO)5WL (3a - 3c), respectively, in high yields. The palladium(II) complexes PdCl2L2 (4a - 4c) are obtained on treatment of 1a, 1b and 1e with 1,5-cyclooctadiene palladium(II) chloride or anhydrous palladium(II) chloride in a homogeneous or heterogeneous reaction, respectively. 4a - 4c are formed as a mixture of cis- and trans-isomers. The 13C{1H} NMR and 1H NMR spectra of 2a - 4c have been analysed, the trans-structure of 4c could be assigned to the predominant isomer. The X-ray structural analysis of 4c (triclinic, space group P1) reveals a trans-square planar coordination at palladium with an antiperiplanar arrangement of the bulky tBu substituents at the phosphorus atoms. Electronic (∑xiMo) and steric ligand parameters (θ) are given for the chloromethylchlorophosphines R(Cl)P-CH2-Cl (R = Cl, tBu, C6H11,NEt2,NPh2).
