Stoichiometric Alkane Dehydrogenation with Tp‘PtMe₂H to Form Tp‘Pt(<i>η</i>²-olefin)(H) Complexes

Abstract

Gentle heating of Tp‘PtMe 2 H ( 1 ) in alkane solvents in the presence of B(C 6 F 5 ) 3 results in C−H activation of the alkane solvent, R−H, to give Tp‘Pt(Me)(H)(R) intermediates. Further heating leads to formation of Tp‘Pt(η 2 -olefin)(H) complexes via methane elimination followed by β-hydride elimination, a stoichiometric alkane to olefin conversion.
