Isobutyric Acid → 4-Methyl-1,2lambda~6~-oxathiolane-2,2,5-trione

Participants

Reaction Steps

88 g. of isobutyric acid dissolved in 100 g. of sulfuryl chloride is heated at 80° C. and irradiated with a 300 watt tungsten lamp for 2 hours. Addition of ligroin precipitates an oil which has a boiling range 135°-140° at 4mm and is identified as 4-methyl-1,2-oxathiolane-5-one-2,2-dioxide by its equivalent weight, 75.
