Feeling the pinch: Remarkably facile Si[BOND]C(sp3) and Si[BOND]C(sp2) bond cleavage processes occur in [(Cy[BOND]PSiP)M(alkyl)] species (M=Ni, Pd; see picture); in the case of Ni, these Si[BOND]C bond activation processes are reversible on the NMR timescale in solution. Such examples of metal-mediated cleavage of an unstrained Si[BOND]C(sp3) bond are extremely rare and are unprecedented for Ni.
