Abstract

Various N‐nitrosamines were photolyzed in toluene solution in the temperature range −100°C to −30°C to yield dialkyl nitroxides. The nitrosamines studied were N‐nitrosodimethylamine, N‐nitrosodiethylamine, N‐nitrosodipropylamine, N‐nitrosodibutylamine and N‐nitrosodicyclohexylamine. Subsequent nitroxide side products were also detected by ESR, and a mechanism for their formation is proposed. Temperature dependent hyperfine couplings of the methylene protons were observed for a few radicals of the type R~1~CH~2~NO^˙^R~2~.

The photoreaction of systems containing N-oxides and amines has been studied by ESR. The lowest triplet state of the heteroaromatic N-oxide combines with triethylamine to form an exciplex. Oxygen transfer and a-cleavage of the N-C bond in the amine part of the exciplex gave diethyl nitroxide.
