Reaction of aromatic isocyanides with triethylamine: a new method for the synthesis of indole betaines
Abstract
A new reaction between aromatic isocyanides containing electron-withdrawing substituents and triethylamine is described which allows 2-triethylammonium-3-arylaminoindolates to be obtained. The structure of the compounds was determined by X-ray analysis, NMR and mass spectroscopy.
