Different but almost equal : The striking similarities between Brookhart's iridium(III) pincer complex and the electron‐deficient tris(pentafluorophenyl)borane in transformations involving SiH bond activation are highlighted. Coordination of the SiH bond to either Lewis acid enhances the electrophilicity of the silicon atom, thereby enabling its transfer to various Lewis basic groups (see scheme, Do=acetone).
