<b>Thermal decomposition of vinyl- and allylsilane platinum(II) complexes and platinum(II) catalysed synthesis of (<i>E</i>),(<i>E</i>)-1,4-diphenyl-1,3-butadiene</b>

Abstract

Thermal stabilities of Pt(II) complexes: K[PtCl3(CH2=CHSiMe3)], K[PtCl3(CH2=CHCH2SiMe3)], K[(acac)PtCl(CH2=CHSiMe3)] and [PtCl(CH2=CHCH2SiMe3)]2, were examined. All complexes were found to be stable at room temperature but they decomposed without melting above about 90 oC. The allylsilane complex decomposed above about 125 oE),(E)-1,4-diphenyl-1,3-butadiene was stereoselectively synthesised in good yield from (E)-β-styrylsilane in the presence of Zeise’s salt.
