Procedure

Into a sealed tube in which air was replaced by nitrogen were placed 1.50 g (7.4 mmoles) of 2-methylbenzoselenazole and 3.34 g (7.5 mmoles) of octadecyl parachlorobenzenesulfonate. The resulting mixture was heated at 130° C. for 5 hours. The reddish purple solid obtained was washed with ether and recrystallized from n-propanol, giving 2.40 g (yield: 50.5%) of 2-methyl-3-octadecylbenzoselenazolium parachlorobenzenesulfonate as a reddish purple powder.
