Synthesis, structural characterization and reactivity towards methanol of a bis(silyl)platinum(II) complex bearing a chelating depe ligand.

Treatment of 1,2-C 6 H 4 (SiH 3 )(SiH 3 ) ( 1 ) with [Pt(depe)(PEt 3 ) 2 ] (depe = Et 2 PCH 2 CH 2 PEt 2 ) in the ratio of 1:1 yields the complex [Pt II {1,2-C 6 H 4 (SiH 2 )(SiH 2 )}(depe)] ( 2 ), which has unique reactivity towards sterically unhindered alcohol to form an unusual tetra-alkoxy substituted silyl platinum(II) compound ( 3 ). Only 2 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 multinuclear NMR spectroscopic studies and single crystal X-ray analysis. [ABSTRACT FROM AUTHOR]
