Procedure

Methyl viologen hydrochloride (1.17 g) in N,N-dimethylformamide (80 mL) at 25° C. was saturated with trifluoromethyl iodide, treated with 2-fluorobenzenethiol (9.7 mL) and triethylamine (20 mL), stirred for 24 hours, diluted with water (240 mL) and extracted with diethyl ether. The extract was washed with 1M NaOH, saturated ammonium chloride and brine and concentrated.
