Abstract The iron(III) chloridepromoted desulfitative C–C coupling of α-oxo ketene dithioacetals with indoles was developed for the synthesis of indole derivatives. In the presence of iron(III) chloride, α-oxo ketene dithioacetals reacted efficiently and highly selectively with C2-unsubstituted or C2-substituted indoles to afford excellent yields of β,β-bisindolyl or β-indolyl α,β-unsaturated carbonyl
