Exposure of dilute solutions of various dialkyl and cyclic N-chloro amines in trichlorofluoromethane to (60)Co γ-rays at 77 K gave the corresponding cations, R2N.Cl, characterised by (14)N, (35)Cl, and (1)H hyperfine coupling.The results suggest that these radicals are essentially planar at nitrogen, the SOMO being the N-Cl ?* orbital.Similar treatment of dilute solutions in methanol or methyltetrahydrofuran gave the corresponding amino radicals, R2N., also characterised by their e.s.r. spectra.There was no evidence for the formation of the parent radical anions.These results are contrasted with those for N-halogeno imides and the formation of ?* radicals from the cations R3N. and halide ions.
