Synthesis and Reactivity of a Cationic Platinum(II) Alkylidene Complex

Often proposed, hard to catch: The bis(platinacycle) trans-[Pt{P[2,6-(CH2)(Me)C6H3]iPr2}2] experiences α-hydride abstraction by action of Ph3C+PF6− to yield a trans-alkyl–alkylidene species. The electrophilicity of its {PtCH}+ unit is demonstrated by ylide formation by reaction with Lewis bases, stepwise hydrogenation, and carbene cross-coupling with N2C(H)CO2Et (see scheme).
