Formation of crossed phenazine from the reaction between tetra-p-anisyl- and tetra-p-tolyl-hydrazines in liquid sulphur dioxide

Abstract

On dissolving tetra-p-anisyl- and tetra-p-tolyl-hydrazines in liquid sulphur dioxide in the dark in the absence of oxygen, the tetra-p-anisylhydrazine cation radical was formed and 2-methoxy-7-methyl-5-p-anisyl-10-p-tolyl-5,10-dihydrophenazine was isolated from the reaction mixture.
