摘要：

Treatment of OsCl2(PPh3)(3) with 1,3-(PPh2CH2)(2)C6H4 led to the formation of the coordinatively unsaturated complex OsCl(PPh3)(PCP) (PCP = 2,6-(PPh2CH2)(2)C6H3). Reactions of OsCl(PPh3)(PCP) with RC=CH (R = Ph, t-Bu, C(OH)Ph-2) gave OsCl(=C=CHR)(PPh3)(PCP). Treatment of OsCl(=C=CHPh)(PPh3)(PCP) and OsCl(=C=CHC(OH)Ph-2)(PPh3)(PCP) with HCl produced the carbyne complexes OsCl2(=CCH2Ph)(PCP) and OsCl2(=CCH=CPh2)(PCP), respectively. The solid-state structures of OsCl(PPh3)(PCP) and OsCl(=C=CHPh)(PPh3)-(PCP) have been determined by X-ray diffraction.
