| dc.description.abstract | Syntheses of several spiro[benzo[b]thiophen-6(5H), 1'-cycloalkan]-4(7H)-ones (Type A) and spiro[benzo[b]thiophen- 5, 1'-cycloalkan]-4(5H)-ones (Type B) and their 2-alkyl derivatives are described. The regioselectivity in the Friedel-Crafts acylation of thiophenes with anhydride of various unsymmetrically substituted succinic acid having substituent(s) at the same carbon atom in two different solvents namely dichloromethane and nitrobenzene is studied. A plausible explanation of such regioselective acylation of thiophenes has been incorporated. | en_US |
