Sultine
In chemistry, a sultine is a cyclic ester of a sulfinic acid. This class of organosulfur compounds has few applications. These compounds are typically prepared by the dehydration of hydroxy-sulfinic acids or their equivalent. Illustrative of an alternative route, xylylene dibromide reacts with sodium sulfoxylate to give the sultine C6H4, which is a precursor to o-quinodimethane.
