Abstract

The dichloro(dihydrido)osmium(IV) and dichloroosmium(II) compounds 4 and 5, which contain the hemilabile chelating phosphinoester Pri2PCH2CO2Me 2 as ligand, react with alkynols HCCCPh(R)OH (R = Me, Ph) to give the octahedral carbynedichloroosmium(II) complexes 7 and 8; the related starting material 6 with Pri2PCH2CH2NMe23 as ligand on treatment with HCCCPh2OH yields a carbyne(dichloro)hydrido compound, and with HCCPh a vinylidene osmium(II) derivative.
