Photoinduced reactions of PtCl62– with saturated hydrocarbons and other C–H containing compounds

Abstract

Light irradiation of a solution of PtCl₆^2– and an n-alkane (hexane or heptane) in MeCO₂H or CF₃CO₂H–H₂O yields the corresponding π-olefin complex of Pt^II, the formation of which is assumed to proceed via a σ-alkyl complex of Pt^IV; the reaction with acetone, which has no β-hydrogen atoms affords a stable σ-acetonyl complex of Pt^IV and σ-aryl complexes are formed on irradiation of PtCl₆^2– with arenes.
