An inexpensive and environmentally friendly FeCl3 catalyzed Friedel-Crafts alkylation of α-hydroxy ketene dithioacetals with indoles including free-NH indoles and N or C(2)-substituted indoles has been developed. The reaction was efficiently performed in the presence of FeCl3 (2.5 mol%) at room temperature (25 ℃) in CH2Cl2, affording α-indolyl ketene dithioacetals in excellent yields. The procedure was characterized by lower amount of inexpensive catalyst, mild reaction condition, environmentally benign and similicity.

Key words: iron (III) chloride, ketene dithioacetals, alcohols, indole derivatives, Friedel-Crafts alkylation
