The reaction of N,N-dimethylaniline with aluminum chloride in vacuo has given a deep blue solution. This blue solution turns violet because of moisture or the added methanol. The electronic spectra of these solutions seem to be identical with that of crystal violet. The finding that transient green species appear when the vacuum cell system is opened to air can be interpreted in terms of the color of crystal violet dissolved in hydrochloric acid. From these findings the formation of crystal violet has been concluded.
