Activation of Si–H and B–H bonds by Lewis acidic transition metals and p-block elements: same, but different
Pablo Ríos, Amor Rodríguez, Salvador Conejero
Abstract
) favors this type of bond activation that can lead to reactivities involving the formation of transient silylium and borenium/boronium cations similar to those proposed in silylation and borylation processes catalysed by boron and aluminium Lewis acids. We compare the reactivity of transition metal complexes and boron/aluminium Lewis acids through a series of catalytic reactions in which pieces of evidence suggest mechanisms involving electrophilic reaction pathways.
