Reaction of 1,1-disubstituted hydrazines with dibromoisocyanurate in the presence of nitrosobenzene

A study was carried out on the reaction of 1,1-disubstituted hydrazines with dibromoisocyanurate in the presence of nitrosobenzene. Depending on the structure of the hydrazine component, the reaction may proceed either to 3,3-disubstituted 2-phenyltriazene 1-oxides or the products of the oxidative dimerization of hydrazine derivatives, namely, 1,1,4,4-tetrasubstituted tetrazenes.
