The rates of acid cleavage of (pentafluorophenyl)trimethyl-stannane and -silane have been measured. For the first compound the rate is markedly larger than would be expected for additivity of the deactivating effects of the five fluorine atoms separately. For the second, the rate is not significantly less than that expected for such additivity, and is probably somewhat greater.
