Estimation of the rate constants for the radical addition of a trifluoromethyl radical to aryl-substituted vinyl triflates

Abstract

The rate constants for the radical addition of a trifluoromethyl radical to aryl-substituted vinyl triflates have been determined by applying competition kinetics at a single concentration point. The rate constants range from 4.1 × 106 to 5.6 × 106 M−1 s−1 and depend on the electronic properties of the benzene rings on the aryl-substituted vinyl triflates.
