Abstract

The synthesis of 2-aroyl-3,5-diarylthiophenes has been achieved from various 1,5-diketones with elemental sulphur and morpholine under efficient microwave conditions. The reaction follows a green protocol involving solvent-free conditions, short reaction time, and simple work-up avoiding chromatographic purification.
