Silicon Chemistry In earlier studies, the bis(amidinato)silylene [ i PrNC(Ph)N i Pr] 2 Si has been demonstrated to react with PhSe−SePh in terms of a “homolytic activation” of the Se−Se bond to give a six‐coordinate silicon(IV) complex with two selenophenolato ligands (see scheme). Interestingly, the analogous bis(guanidinato)silylene [ i PrNC(N i Pr 2 )N i Pr] 2 Si reacts with PhS−SPh and PhSe−SePh in terms of a “heterolytic activation” of the S−S and Se−Se bond to afford ionic five‐coordinate silicon(IV) complexes with one thiophenolato and one selenophenolato ligand, respectively, and a PhS − or PhSe − counterion (see scheme).
