Treatment of OsCl 2 (PPh 3 ) 3 with 1,3-(PPh 2 CH 2 ) 2 C 6 H 4 led to the formation of the coordinatively unsaturated complex OsCl(PPh 3 )(PCPTreatment of OsCl(dCdCHPh)(PPh 3 )(PCP) and OsCl(dCdCHC(OH)Ph 2 )(PPh 3 )(PCP) with HCl produced the carbyne complexes OsCl 2 (tCCH 2 Ph)(PCP) and OsCl 2 (tCCHdCPh 2 )(PCP), respectively. The solid-state structures of OsCl(PPh 3 )(PCP) and OsCl(dCdCHPh)(PPh 3 )-(PCP) have been determined by X-ray diffraction.

Treatment of o-Ph 2 PC 6 H 4 CHO with 6-H 2 NCH 2 CH 2 NH-β-CD (CD ) cyclodextrin) produced 6-(o-Ph 2 PC 6 H 4 CHdNCH 2 CH 2 NH)-β-CD (CDNNP), which reacted with MCl 2 (COD) (M ) Pd, Pt) and [PdCl(η 3 -C 3 H 5 )] 2 to give [MCl(CDNNP)]Cl and [PdCl(η 1 -C 3 H 5 )(CDNNP)]Cl, respectively.
