Reactions of fluoroalkyl radicals generated electrochemically. Part 2. Addition of heptafluoropropyl radicals to methyl methacrylate
Abstract
Heptafluoropropyl radicals, generated by the electrolysis of heptafluorobutyric acid, reacted with methyl methacrylate to give a mixture of products of the type RFCH2CH(Me)X, RFCH2C(Me)(RF)X, [RFCH2C(Me)X]2 and RFCHC(Me)X, where RF= C3F7 and X = CO2Me. Also formed by electrochemical oxidation of the product of the intial radical addition reaction were CH2C(CH2RF)X, (RFCH2)2CHX, and (RFCH2)2C(RF)X, this being the preferred process. A trimeric and second dimeric product were also formed.
