Abstract

The aim of the present work was to study the synthetic possibilities of the recyclization of nitropyridi- nium salts. The rearrangement of nitropicoline and nitrolutidine salts into nitroanilines was carried out for the first time in the eighties [2–4]. In the early stages of investigations on drawing up a scheme for the recyclization of nitropyridinium salts the formation of anhydro bases A and anionic σ-complexes B as intermediates were postulated. ...
