Thiobenzoic anhydride

Dlbenzoyl sulfide (Thiobenzoic anhydride. Benzoyl sulfide) 48, al 133, 128 ... [Pg.425]

Benzoyl disulfide has been obtained by the reaction of benzoyl chloride with hydrogen sulfide, hydrogen disulfide, hydrogen trisulfide, potassium sulfide, sodium disulfide, lead sulfide, sodium hydrosulfite, sodium thiosulfate, sulfhydrylmagnesium bromide, and thiobenzamide. It is also formed by reaction of benzoic anhydride with hydrogen sulfide. The better preparative methods involve the oxidation of thiobenzoic add by means of air,hydrogen peroxide or sulfur monochloride, or of the sodium or potassium salt by means of air, - chlorine, iodine, copper sulfate, - potassium ferricyanide, - or ferric chloride. - ...

Thiocarboxylic acids are obtained by acylation of hydrogen sulfide (cf. page 642). For example, thiobenzoic acid is formed (61-76% yield) from benzoyl chloride and potassium hydrogen sulfide,426 and thioacetic acid (74% yield) when hydrogen sulfide is passed into acetic anhydride.427,428 This method can also be applied to other anhydrides.429...
