摘要

Trifluoroethanol was oxidized with O_2 to trifluoroethyl trifluor-acetate (＞98% selectivity) using Pt~Ⅱ(dppz)CI_2 as a catalyst in the presence of H_2SO_4;Pt~Ⅱ(phen)CI_2 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.
