Hydrogen atom abstraction by tert-butoxy radicals from hydrazine, methyl-, benzyl-and carboethoxy-hydrazine yields the hydrazyl radical and the appropriate 1-substituted hydrazyls, [Formula: see text] The radical structures are assigned on the basis of their e.p.r. spectral parameters. It has been shown by 15 N labelling that in 1-alkylhydrazyls the larger nitrogen splitting is produced by the divalent nitrogen that formally bears the unpaired electron. This result contrasts with the behavior of 2,2-dialkylhydrazyls (1).
