The carbanions resulting from the deprotonation by nBuLi of compounds of the type [M(CO)4(Ph2PCH2PPh2)] (M Cr, Mo or W) are readily organomercurated by RHgCl [R e.g. Me, Et, Ph, or (C5H4)Fe(C5H5)] to give neutral complexes of the type [M(CO)4∗[Ph2PCH(HgR)PPh2∗]]. The X-ray crystal structure of the complex with M Cr and R Me has been determined, and reveals intermolecular C ··· O hydrogen bonding
由[ n(n) BuLi对[M(CO)4(Ph 2 PCH 2 PPh 2)]类型的化合物(MCr,Mo或W)进行质子化而产生的碳负离子很容易被RHgCl [R Me例如Me,Et ,Ph或(C 5 H 4)Fe(C 5 H 5)]产生[M(CO)4 * * [Ph 2 PCH(HgR)PPh 2∗]]。已确定了具有MCr和RMe的配合物的X射线晶体结构,并揭示了分子间C···O氢键与羰基氧受体原子的键合作用以及羰基氧与氢之间的弱次级分子间相互作用。汞原子。
