H[PtCl3(C4H8)], prepared by reduction of H2[PtCl6] with n-butanol reactswith 2-pentylene to give equal amounts of the regioisomers [PtCl2(C4Et2 Me2)] (3a, 3b). An equimolar mixture of 2-butyne/3-hexyne reacts under the same conditions to give [PtCl2(C4Me4)] (1), [PtCl2(C4Et4)] (2) and [PtCl2(C4Et2Me2)] (3a) in a molar ratio 1:1.3:6.6. 1 and 2 react with ligands L (L= py a, p-tol b, PPh3 c, AsPh3 d, SbPh3 e) to give complexes ofthe type [PtCl2(C4R4)L]. The complexes were characterized by microanaly sis as well as by i.r., (1) H- and (13) C n.m.r. spectroscopy.
