Abstract: Selectivity ratios for photodifluoramination of n-butane, n-butyl fluoride, ethyl chloride, and ethyldifluoramine were determined by analyzing the isomeric mixture of alkyldifluoramines produced by irradiation of N2F4 with these substrates. Kinetic and stoichiometric information about the photodifluoramination process was obtained from a study of the photolysis of N2F4 with methane. Irradiation of N2F4 with propylene and ...
