Abstract
The solid-state reaction between anilines and phenacyl bromides in the presence of an equimolecular amount of sodium bicarbonate or a second equivalent of the aniline followod by microwave irradiation provides a mild, general, and environmentally friendly method for the synthesis of 2-arylindoles in good overall yields.
