Reaction Conditions:

with ferrocene;sulfur dioxide at 100; under 5250.53 - 20252 Torr; for 1 h;Product distribution / selectivity;

Steps:

3
Except that the amount of ferrocene used in manufacturing of sulfolene was changed to 0.019 g (0.10 mmol) , a 3-sulfolene aqueous solution was prepared in the same manner as in Example 1. The amount of 3-sulfolene in the obtained aqueous solution was 104 g (0.88 mol) and the yield from 1,3-butadiene was 88%. Polymers were not found on the filter paper after filtering the 3-sulfolene aqueous solution. Next, the obtained 3-sulfolene aqueous solution was hydrogenated in the same manner as in Example 1. The reaction time was 98 minutes and the reaction was 100% progressed. Table 1 shows the measurements of the amount of generated polymers and the reaction time of hydrogenation.
