Indium hydroxide → Indium(III) Bis-triflimide

Participants

Reaction Steps

5.0 g of Indium (III) hydroxide was dissolved in 50 ml of water and to which 27.0 g of HNTf2 was added and stirred at room temperature for 24 hours. The reaction mixture was filtered and the filtrate was concentrated on a rotary evaporator and dried under vacuum (1 mmHg) for 3 days at 120° C. The unpurified indium(III) bis-triflimide was found to be an excellent Friedel-Crafts catalyst for the reaction of toluene, anisole and xylene with benzoyl chloride or benzoic anhydride.
