The reactions of NH radicals with C 4 olefins, trans-and cis-2-butenes, 1-butene, and isobutene, were investigated by the photolysis of hydrogen azide in the liquid olefin at 0° C and at the temperature of Dry Ice–methanol. Except for nitrogen and ammonia, amines and aziridines were found to be formed in good yield. 2-Butene-1-amine and trans-2, 3- dimethylaziridine from trans-2-butene, 2-butene-1-amine and cis-2, 3-dimethylaziridine ...
