“…The photolysis of azoalkanes 1 in 1,4-cyclohexadiene afforded quantitatively the hydrazoalkanes 4 , which for isolation and characterization were trapped as the derivatives 5 (eq 1) by treatment with ethyl chloroformate and triethylamine. Furthermore, exposure of the photolysates to air over a period of 2−3 days regenerated the azoalkanes 1 by oxidation of the hydrazines 4 , as monitored by 1 H NMR analysis .…”

“…The cyclic hydrazines such as 4 are very sensitive toward oxidation, and hence, their characterization is mainly based on NMR spectral data . However, the autoxidation of the hydrazines 4 to the precursor azoalkanes 1 , and their trapping with ethyl chloroformate 7,13 to afford the carbamates 5 (eq 1), which have been fully characterized, provide unambiguous structural evidence. Only for the azoalkane 1d , the thermal as well as acid lability of the carbamate derivative 5d precluded its isolation for full characterization.…”

“…Among the various less explored topics of research in this field are the reactions of substituted hydrazines with ozone. Although the oxidation of both aliphatic and aromatic hydrazines with various oxidants has been extensively studied, , there are only a few reports on the ozonation of these compounds, which date back to the early 20th century. Molinari4a as well as Strecker and Baltes 4b studied the ozonation of 1,2-diphenylhydrazine (hydrazobenzene) and reported 1,2-diphenyldiazene (azobenzene) to be the only reaction product (for a summary of these studies, see ref ).…”
