Synthesis, structural characterization and reactivity towards phenol of a bis(silyl) platinum(II) complex

An unusual diphenoxy substituted (bis)silyl platinum(II) complex 3 bearing a chelating dmpe ligand by successive oxidative addition, reductive elimination and dehydrocoupling reaction of a kind of poly(silyl) chelating hydrosilane has been established. We report the synthesis and rarity of the molecular structure of this new silyl-transition-metal complex which is one of the very few examples of bis(silyl) platinum(II) complexes derived from this chelating hydrosilane ligand registered in the Cambridge Structural Database.
