Ma. Mironov et Vs. Mokrushin, Reaction of aromatic isocyanides with triethylamine: a new method for the synthesis of indole betaines, MENDELEEV C, (6), 1998, pp. 242-243
A new reaction between aromatic isocyanides containing electron-withdrawing
substituents and triethylamine is described which allows 2-triethylammoniu
m-3-arylaminoindolates to be obtained. The structure of the compounds was d
etermined by X-ray analysis, NMR and mass spectroscopy.
