... As an alternative to the generation of cationic complexes, the strong Lewis acid B(C6F3)3 could be used to abstract a methyl anion from Cp2MMe2 to give [Cp2MMe][MeB(C6F5)3] (Scheme 3, reaction 4)48. Residual coordinative contacts between the cationic metal center and the anion via the abstracted met ...
