To a solution of 340 mg (5 mmoles) of imidazole in 5.0 ml of dry DMF were added 606 mg (1 mmole) of 3-p-toluenesulfonyloxy-1,1,2-triiodo-1-propene and the reaction was effected at 25° C. for 2 hours. The reaction mixture was poured into 20 ml of ice-water while stirring vigorously and the mixture was allowed to stand for a further one hour. The crystalline substance thus separated was recovered by filtration, washed with water and then dried. Yield 440 mg (96%), mp 127°-128° C. (with decomposition).
