Santschi, Nico; Nauser, Thomas published the artcile< Rate of single electron reduction of Togni's reagent>, Recommanded Product: (9Z,12Z)-Methyl octadeca-9,12-dienoate, the main research area is Togni reagent single electron reduction rate.
We report on the rate of reduction of a popular electrophilic trifluoromethylating agent, Togni’s reagent (T-CF3), with solvated electrons (e-aq) generated by pulse radiolysis. By means of competition experiments against Me viologen (MV2+) and direct observation of the decay of e-aq we determined k(T-CF3 + e-aq) ≈ 2 × 1010 M-1 s-1. To the best of our knowledge, this constitutes the first report on a reduction of T-CF3 with an unambiguously clear outer-sphere mechanism. Furthermore, we studied the oxidation of 2-(2-iodophenyl)propan-2-ol (ROH) by peroxyl-radicals to a presumably cyclic iodanyl radical RI·. This species RI· was not detected during the reduction of T-CF3 with e-aq and therefore, this reduction does not proceed via heterolytic I-CF3 bond cleavage to CF3- and RI·. More likely, a CF3 radical is formed, as was observed in numerous synthesis studies reported to date.
