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 (source of SO₂^2-) to give the sultine C₆H₄(CH₂S(O)OCH₂), which is a precursor to o-quinodimethane.^[1]
