The complex trans- reacts with monosubstituted acetylenes HCCR (R=CH2OH, CH(OH)Me, C(OH)Me2, C(OH)MeEt, CH(OH)Ph, C6H10OH,Ph, or CMe=CH2) in the presence of NEt2H to give trans-CR)(PPh3)2>, which have been characterized by i.r., u.v., and n.m.r. spectroscopy.An X-ray diffraction analysis was carried out on C-C(OH)MeEt>(PPh3)2>.Crystals are monoclinic, space group P21/n, with unit cell dimensions a=15.560(3), b=26.696(5), c=9.038(2) Angstroem, β=98.51(2) deg, Z=4.A total of 3855 observed reflections have been measured by single-crystal diffractometry and refined by blocked full-matrix least squares to R=0.067.Co-ordination around platinum is distorted square planar and involves the acetylide ligand trans to hydrogen which was directly located.In some reaction conditions cationic intermediates have been demonstrated by conductivity measurements.
