Longitudinally extended molecular wires based upon PtC equivalent to CC equivalent to CC equivalent to CC equivalent to C repeat units: Iterative syntheses of functionalized linear PtC8Pt, PtC8PtC8Pt, and PtC8PtC8PtC8Pt assemblies

摘要

Condensations of (p-tol(3)P)(2)PtCl2 with Me-3-SnCequivalent toCCequivalent toCSiMe(3) and HCequivalent toCCequivalent toCSiMe(3) give mono- or bis((trimethylsilyl)butadiynyl) complexes that are desilylated and elaborated by oxidative cross-couplings and homocouplings to give the title compounds trans-Cl[(ptol(3)P)(2)PtCequivalent toCCequivalent toCCequivalent toCCequivalent toC](m)Pt(P-p-tol(3))(2)Cl (m = 1-3).
