Symmetrically and unsymmetrically substituted di(arylmethyl)aminonitrenes, generated by thermolysis of the potassium salts of the respective methanesulfonohydrazides, dissociate in methanol, cyclohexanol, and dimethyl sulfoxide with the formation of nitrogen, 1,2-diarylethanes, and diarylmethanes.Unsymmetrically substituted di(arylmethyl)aminonitrenes form the products from crossed coupling of the arylmethyl radicals.The magnitude of the cage effect was determined for the pair of arylmethyl radicals, and the effect of the viscosity of the solvent on the yield of the cage recombination product was investigated.

The mechanism of the dissociation of dibenzylaminonitrene and p-bromodibenzylaminonitrene into molecular nitrogen and hydrocarbon products was studied.Dibenzylaminonitrene forms dibenzyl and o- and p-benzyltoluenes.In the presence of thiophenol significant amounts of toluene are formed.During dissociation p-bromodibenzylaminonitrene gives a mixture of symmetrical and unsymmetrical dibenzyls.In the presence of octanethiol only unsymmetrical p-bromodibenzyl is formed.The dissociation of dibenzylaminonitrene takes place by synchronous cleavage of the two C-N bonds and the formation of a pair of benzyl radicals.Dibenzylaminonitrene dissociates from the singlet electronic state.

By ESR with spin traps it was shown that the dissociation of dibenzylaminonitrene to nitrogen and bibenzyl takes place through the formation of benzyl radicals.Various methods of generation of dibenzylaminonitrene in the presence of spin traps (2-methyl-2-nitrosopropane, nitrosodurene, phenyl-N-tert-butyl-nitrone) give spin adducts (nitroxyl radicals) stable at room temperature.The formation of two nitroxyl radicals during the dissociation of dibenzylaminonitrene labeled at one methylene group with deuterium imdicates that one molecule of dibenzylaminonitrene gives two benzyl radicals during dissociation.
