  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 (source of $SO_2^{2-})$ to give the sultine $C_6H_4(CH_2S(O)OCH_2),$ which is a precursor to o-quinodimethane.
