    • 6 was diluted in dichloromethane and filtered through a Celite pad to remove the inorganic materials followed by stirring for 2 h with charcoal to remove the light green color. After this time, the solution was filtered, concentrated, and subjected to the vacuum for 1 h to eliminate the moisture and trace of organic solvents. For the following runs the recovered ionic liquid was used after the addition of one equivalent of indium powder (1 mmol, 115 mg), diphenyl diselenide (0.5 mmol, 156 mg), and benzoyl chloride (1 mmol, 141 mg). Then, the product was extracted as described above
