Abstract

Abstract: In acidic 60% aqueous dioxane solution at 0" C, 4, 4'-dichlorohydrazobenzene (18) undergoes concurrent disproportionation, to p-chloroaniline (19) and 4, 4'- dichloroazobenzene (20), and 0-(21) and p-semidine (22) rearrangement. In the p-semidine rearrangement one of the chlorine atoms of 18 is displaced, in essence, as C1+. This requires participation of a second molecule of 18 in a redox reaction. The overall fate of 18 ...
