Procedure

Into a sealed tube in which air was replaced by nitrogen were placed 0.50 g (2.17 mmoles) of 5-methoxy-2-methylbenzoselenazole and 1.06 g (2.39 mmoles) of octadecyl parachlorobenzenesulfonate. The mixture obtained was heated at 130° C. for 4 hours. The resulting reddish purple solid was washed with ether and dried under reduced pressure, giving 0.72 g (yield: 49.3%) of 5-methoxy-2-methyl-3-octadecylbenzoselenazolium parachlorobenzenesulfonate as a reddish purple powder.
