Synthesis of allyl aryl sulphides by palladium(0)-mediated alkylation of thiols

Simple and convenient synthesis of 2-(substituted-benzylsulfanyl)-4,5-dihydrothiazoles and their antimicrobial activity studies

“…Generally these reactions require very long refluxing time and yields obtained are often very low [12]. Several other methods employed for preparing thioethers include Pd(0) mediated alkylation [13], phase-transfer catalysis [14], bis(diphenylstannyl)telluride [15], tin sulfides with aryl halides [16], ligand transfer reactions [17], clay catalysis [18], trifluoroacetic acid [19] and the use of strong base like n-BuLi has also been reported [20]. Recently use of CsF-Celite condition has also been reported for the S-alkylation [21].…”

Synthesis of Diversified Thioethers, 1-Aroylalkylisoquinolin-1-yl Thioethers, by Electrophilic S-Alkylation of 3-Phenyl Isoquinoline-1(2H)-thione

“…[4][5][6][7] Many syntheses have been reported for the preparation of thioethers. [8][9][10][11][12][13][14][15][16][17][18] Commonly employed methods are the alkylation of thiols. [19][20][21][22] Thioethers have been prepared by many methods; however, the synthetic scope is often hampered by use of expensive materials, high temperature, hazardous and corrosive compounds such as alkylating agents and strong reducing agents, harsh reaction conditions, and tedious workup procedures, resulting in low product yield.…”

Rapid and Regiospecific Phenylthiolation of Some Organic Acids Catalyzed by AlCl3 in the Presence of Excess Anhydrous ZnCl2

“…[5] Sometimes, the reactions require very long refluxing time. Now, various methods have been employed including palladium(0)-mediated alkylation, [6] phase-transfer catalysis, [7] bis(diphenylstannyl) telluride, [8] tin sulfides with aryl halides, [9] ligand transfer reaction, [10] montmorillonite clay, [11] and CsFCelite [12] catalysis. Recently, Yin and Pidgeon [13] reported a facile method for the preparation of unsymmetrical sulfides using very strong n-BuLi.…”
