In a thionoester, sulfur replaces the carbonyl oxygen in an ester. Methyl thionobenzoate is C6H5C(S)OCH3. Such compounds are typically prepared by the reaction of the thioacyl chloride with an alcohol. They can also be made by the reaction of Lawesson's reagent with esters or by treating pinner salts with hydrogen sulphide.
