The Photochemistry of Nitramines, I: Preparation of Nitroxides in Solution and in Situ in Single Crystals.
Abstract
Ultraviolet irradiation of cyclic nitramines, both in solution and as single crystals, reveals an EPR signal due to nitroxide radicals. Photolysis of solutions of nitramines in 1,3-propanediol cyclic carbonate in the EPR cavity allowed preparation and assignment of the spectra of pyrrolidine N-oxide, piperidine N-oxide, morpholine N-oxide, 4-methyl-piperidine N-oxide, 4-t-butylpiperidine N-oxide, 4-nitro-piperazine N-oxide, 3-nitro-1,3, diazacyclohexane N-oxide, and 3,5-dinitro-1,3,5-triazacyclohexane N-oxide. Photolysis of N-nitropyrrolidine and N-nitro morpholine single crystals led to in situ generation of pyrrolidine N-oxide and morpholine N-oxide respectively, and hyperfine tensors for both nitrogen and hydrogen coupling were assigned.
