摘要:
The synthesis of S(C=CPh)(2) (III) is described. Compound III reacts with one equivalent octacarbonyldicobalt (IV) to yield (PhC=C)S[(eta(2)-C=CPh)Co-2(CO)(6)] (V); with another equivalent of Co-2(CO)(8) (IV) the di-coordinated compound S[(eta(2)-C=CPh)Co-2(CO)(6)](2) (VI) is obtained. Complex VI may also be synthesized directly by reaction of III with two equivalents of Co-2(CO)(8) (IV). The identity of III, V and VI is documented by analytical and spectroscopic (IR, MS, H-1-, C-13-NMR) data and (PhC=C)S[(eta(2)-C=Cph)CO2(CO)(6)] (V) additionally by X-ray analysis.
