资源简介：
The title anion can be conveniently prepared from the cation [W2Cp2(μ-PCy2)(CO)4]+ via the iodo complex [W2Cp2(μ-I)(μ-PCy2)(CO)2], which is easily reduced with Na-amalgam. This anion reacts with different electrophiles both at the W and O sites to give unusual unsaturated molecules such as the hydride [W2Cp2(H)(μ-PCy2)(CO)2], methoxycarbyne [W2Cp2(μ-COMe)(μ-PCy2)(μ-CO)], triphenyltin [W2Cp2(μ-SnPh3)(μ-PCy2)(CO)2], and phosphinoxycarbyne [W2Cp2(μ-COPtBu2)(μ-PCy2)(μ-CO)] derivatives, all of them exhibiting novel structural features or unparalleled compositions.
