Abstract: Treatment of [OsCl2(PPh3)3] with HC≡CC(OH)Ph2 in benzene at room temperature produces [(PPh 3)2C1Os(μ-Cl)3Os(=C=CHC(OH)Ph 2)(PPh3)2], fac-[OsCl 3(=C-CH=CPh2)(PPh3)2], mer-[OsCl3(≡C-CH=CPh2)(PPh3) 2], and [OsCl2(=C=C=CPh2)(CO)(PPh 3)2]. The latter two complexes are the major products when the reaction is carried out in refluxing toluene. Treatment of [OsCl 2(PPh3)3] with HC≡CC(OH)Ph2 in the presence of HCl produces fac-[OsCl3(=C-CH=CPh 2)(PPh3)2] and mer-[OsCl 3(≡C-CH=CPh2)(PPh3)2]. Treatment of [OsCl2(PPh3)3] with HC=CC(OH)Ph2 in the presence of HPPh3BF4 produces [OsCl2(≡C-CH=CPh2)(H2O)(PPh 3)2]BF4. The structures of all the new complexes have been confirmed by X-ray diffraction.
