It was shown by x-ray crystallographic analysis that the products from the reaction of azomethines with the sulfur dioxide-methylamine system are methylammonium 1-aryl-1-(arylamino)methanesulfonates.In aqueous solutions of the latter the amine fragment is redistributed with the formation of arylammonium 1-aryl-1-(arylamino)methanesulfonates.It was established that all the obtained salts are in equilibrium with the azomethines in solutions.The form of the nucleophile taking part in the reaction with the azomethine is suggested on the basis of the data from the PMR spectra of the methylamine-sulfur dioxide system.
