| heal.abstract | Optimum reaction conditions for the quantitative preparation of the highly reactive 3,4-di(methylene) tetrahydrothiophene-1,1-dioxide are described. The method involves the zinc-induced 1,4-debromination of 3,4-bis(bromomethyl)-2,5-dihydrothiophene-1,1-dioxide in acetone solvent either by using conventional heating, microwave or ultrasonic irradiation. The [4+2] cycloaddition reaction of 3,4-di(methylene) tetrahydrothiophene-1,1-dioxide with dienophiles such as DMAD and C-60 led to the efficient and clean formation of the corresponding Diels-Alder cycloadducts. Specifically for [60]fullerene, the short-chain C-60 monoadduct was formed in a short reaction time and in high overall yield (56%). In contrast, the iodine-induced 1,4-debromination using KI in toluene, in the presence of 18-crown-6 as a phase transfer catalyst, failed to give the corresponding [4+2] C-60 monoadduct at room temperature or in refluxing toluene and a low product yield (13%) was only obtained at a temperature of 45-50 degrees C. | en |
