Cyclization of 1-aryl-4,4,4-trichlorobut-2-en-1-ones into 3-trichloromethylindan-1-ones in triflic acid

Trichloromethyl-substituted enones (1-aryl-4,4,4-trichlorobut-2-en-1-ones, ArCOCH=CHCCl(3), CCl(3)-enones) undergo intramolecular transformation into 3-trichloromethylindan-1-ones (CCl(3)-indanones) in Brønsted superacid CF(3)SO(3)H (triflic acid, TfOH) at 80 °C within 2–10 h in yields up to 92%.
