The systems, bis(p-dimethylaminophenyl)methane (BMM) and tris (p-dimethylaminophenyl) methane (TMM) with o-AH, gave their cations in the presence of oxygen, showing that the oxygen eliminates the hydrogen atoms of the cation radicals derived from BMM and TMM. The reactions of N,N-dimethylaniline (DMA) with o-AH gave rise to isolations of BMM and N-methylaniline, along with the formations of the cation radical of TMB and the crystal violet cation (TMM+). The mechanisms of the reactions are proposed.Read More
