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

Add time:07/22/2019    Source:sciencedirect.com

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.
