Thiolate ions are also useful for the demethylation of certain ethers, esters, amines, and quaternary ammonium salts. Aryl methyl ethers can be cleaved by heating with EtS in the dipolar aprotic solvent DMF ROAr + EtS ArO +EtSR. Carboxylic esters and lactones are cleaved (the lactones give co-alkylthio carboxylic acids) with a thiol and AICI3 or AlBrs. Esters and lactones... [Pg.550]
