Thio benzoic acid

The method described is adapted from the procedures of Kym 3 and Engelhardt, Latschinoff, and Malyscheff.4 Thio-benzoic acid has been prepared by the reaction of benzoyl chloride with potassium sulfide,4 hydrogen sulfide in pyridine,6 6 and magnesium bromide hydrosulfide.7 It is formed from dibenzoyl disulfide with potassium hydrosulfide,4 potassium hydroxide,4 8 and ammonia.9 It is also formed from dibenzoyl sulfide, from phenyl benzoate, and from benzoic anhydride with alcoholic potassium hydrosulfide.4 It has been obtained from dibenzoyl sulfide and hydrogen sulfide,10 carbon oxysulfide and phenyl-magnesium bromide,11 12 dibenzyl disulfide and sodium ethoxide,13 benzyl chloride and sulfur in the presence of potassium hydroxide,14 and benzylthiosulfuric acid and alkali.18 16... [Pg.103]

Dehydration of homoallylic alcohols. 0-Cholesteryl thiobenzoate (1, X ,ax 256, 288, and 420 nm) on irradiation in cyclohexane with a medium-pressure mercury vapor lamp for 12 min. is converted into 3,5-cholestadiene (2) and thio-benzoic acid in quantitative yield. Similar irradiation of O-cholestanyl thiobenzoate results merely in rearrangement to the thiobenzoic acid S-ester hence the elimination reaction appears to require some conjugation in the transition state of the newly formed bond. ... [Pg.583]

Cu complexes with 1,10-phenatroline (phen) ligand catalyzed arylation of thio-benzoic acid in high yields (Scheme 3.48) [86]. In contrast to Arl, which readily reacted with the thiobenzoic acid, only traces of products were observed in the reaction with PhBr. [Pg.86]

Synthesis of Thiono- and Dithio-esters.—Alkylation of Thio- and Dithio-carb-oxylates. Alkylation of thiocarboxylates takes place at the sulphur atom, and thiolesters are the reaction products in almost all cases. The reaction of thio-benzoic acid with diazomethane yields, however, some methyl thionobenzoate, along with a ten-fold amount of the thiolobenzoate, from which it may be cleanly separated by chromatography, On the other hand, silylation of monothio- or monoseleno-carboxylates affords the 0-silyl esters, in contrast to germylation or stannylation, which occur at the sulphur atom. [Pg.177]

A different chemical method for the preparation of 5-thioaldopyranosides was chosen by Hashimoto and coworkers [40] (Scheme 9.2). They converted per-O-benzylated methyl (3-d-glucopyranoside 33 into the open-chain mixed acetal 34, which, in turn, was treated with the Mitsunobu system triphenylphosphine and diethyl azodicarboxylate in the presence of benzoic acid to yield protected 5-thio-L-idopyranosides 35. [Pg.404]
