✦ Synopsis

A simple method has been developed for the synthesis of 4,4'-diarninodiphenylmethane-(2Hq) for analytical purposes in gas chromatography-negative ion chemical ionization mass s ectrometry usin deutero-h drochloric acid in deuterated metkanol. The reaction was aromatic rings was observed after eight days in these conditions, using mass spectrometry (MS) and nuclear magnetic resonance (NMR) spectroscopy.
