The terminal PH2-complex, [Os(PH2)Cl(CO)2(PPh3)2], when treated with (CF2CO)2O gives [OsPH(C[O]CF3)}Cl(CO)2-(PPh3)2] and this compound in dehydrochlorinated by NaH in tetrahydrofuran yielding the putative phosphinidene species, [Os(PC[O]CF3)(CO)2(PPh3)2] which ring-closes to the title compound the solid-state structure of which is proved by X-ray crystallography.
