Abstract

Trifluoroethanol was oxidized with O₂ to trifluoroethyl trifluoracetate (>98% selectivity) using Pt^II(dppz)Cl₂ as a catalyst in the presence of H₂SO₄; Pt^II(phen)Cl₂ was inactive. Kinetic isotope effects suggest the C–H bond activation as the rate determining step and DFT calculations showed different frontier orbitals for Pt^II(dppz) and Pt^II(phen)-based catalysts.
