摘要
The reactions of cis,trans-[M(CO)(2)(PMe3)(2)CH3I] [M = Fe (1), Ru (2)] and cis,traps,cis-[Fe(CO)(2)(PMe3)(2)(CH3)(2)] (3) with B(C6F5)(3) involve Me-abstraction from the metal with formation of reactive species that undergo decomposition processes. In the presence of H2O complex 2 reacts with B(C6F5)(3) forming cis,trans-[Ru(CO)(2)(PMe3)(2)I(HOB(C6F5)(3))] (7) that slowly transforms in cis,trans-[Ru(CO)(2)(PMe3)(2)I(H2O)](+)[(HOB(C6F5)(3))](-) (8), while complex 1 affords the cyclometallate complex trans[Fe(CO)(PMe3)(2)I(=C(Me)-O-B(C6F5)(2)-OH-)] (9) whose molecular structure was investigated by X-ray diffraction studies.
