•Reactivity toward sterically unhindered phenol.•Successive oxidative addition, reductive elimination and dehydrocoupling reaction.•Silyl transition-metal coordination compounds.
The reaction of 1,2-C6H4(SiMe2H)(SiH3) (1) with Pt(dmpe)(PEt3)2 (dmpe = Me2PCH2CH2PMe2) in the ratio of 1:1 yields the complex {1,2-C6H4(SiMe2)(SiH2)}PtII(dmpe) (2), which has unique reactivity towards sterically unhindered phenol to form an unusual diphenoxy substituted (bis)silyl platinum(II) compound (3). Only 6 examples of bis(silyl) platinum(II) complexes prepared from this chelating hydrosilane ligand have been registered in the Cambridge Structural Database. The structure of complex (3) was unambiguously determined by single crystal X-ray analysis and multinuclear NMR spectroscopic studies.
Graphical abstractAn 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.Figure optionsDownload full-size imageDownload as PowerPoint slide
