YieldReaction ConditionsOperation in experiment
96% With sodium t-butanolate;copper(l) iodide; 2.9-dimethyl-1,10-phenanthroline; In toluene; at 110℃; for 24h;Product distribution / selectivity; Example 1bo-Tolylthiophenol (entry 2, Table 1): The general procedure was used to convert 2-iodotoluene and thiophenol to the title product. Purification by flash chromatography (hexane as the eluent) gave the analytically pure product as a clear oil (386 mg, 96% yield). 1H NMR (300 MHz, CDCl3) δ 7.20-7.00 (m, 9H; Ha, Hb, Hc, Hd, He, He', Hf, Hf', Hg), 2.26 (s, 3H; methyl protons). 13C NMR (75 MHz, CDCl3) δ 139.88 (C8), 136.08 (C6), 133.69 (C1), 132.93 (C2), 130.54 (C5), 129.55 (C9, C13), 129.07, (C10, C12), 127.84 (C3), 126.66 (C11), 126.27 (C4), 20.55 (C7). Anal. Calcd. for C13H12S: C, 77.95; H, 6.04; S, 16.01; Found C, 77.87; H, 6.06; S, 15.81.
95% With copper(l) iodide; 3,5-dimethyl-1-((phenylselenyl)methyl)-1H-pyrazole; caesium carbonate; In dimethyl sulfoxide; at 110℃; for 6h; General procedure: To a round-bottom flask was added the following: DMSO (2mL), aryl iodide (1.0mmol) the respective thiophenol (1.0mmol), Cs2CO3 (650mg, 1mmol), selanylpyrazole 2a (13mg, 0.05mmol), CuI (10mg, 0.05mmol). The reaction mixture was stirred for 6h at 110C. The crude product was diluted with water, extracted with ethyl acetate (3×25 mL), dried and purified by column chromatography (hexane:ethyl acetate, 1:99).
93% With 1,10-Phenanthroline; potassium tert-butylate; copper(II) oxide; In water; at 120℃; for 0.5h;Microwave irradiation; Inert atmosphere; General procedure: A 4-mL sealable vial equipped with a magnetic stirrer bar wascharged with KOt-Bu (85.7 mg, 0.75 mmol), CuO (1.99 mg, 0.025mmol), ligand L1 (0.025 mmol), and the appropriate aryl iodide (0.6mmol) under N2. The vial was sealed with a cap containing a PTFEseptum, and the thiol (0.5 mmol) and H2O (0.5 mL) were added by syringe.The mixture was heated at 120 C by microwave irradiationwith stirring for 30 min, then cooled to r.t. and diluted with EtOAc (20mL). The resulting solution was filtered through a pad of silica gel thatwas washed with EtOAc (20 mL). The organic phase was concentratedto give a crude material that was purified by column chromatography(silica gel, hexane).
65% With 1-mesityl-3-(2-(mesitylamino)-2-oxoethyl)-1H-imidazol-3-ium bromide; potassium tert-butylate; palladium diacetate; In dimethyl sulfoxide; at 80℃; for 12h; General procedure: Pd(OAc)2 (6.7mg, 0.03mmol), ligand 1 or 2 (0.036mmol), aryl halides (3.0mmol), thiol (3.0mmol) and NaHMDS (825mg, 4.5mmol) or KOtBu (505mg, 4.5mmol) were combined with DMSO (10mL) in a small round-bottomed flask. The resulting mixture was stirred at 80C for 12h. The reaction mixture was poured into water and extracted with EtOAc. The solvent was removed under vacuum, and the resulting crude product was purified by flash chromatography on silica gel to give the desired product.

YieldReaction ConditionsOperation in experiment
88% To a cooled (-78 C) solution of 2-iodotoluene (6.00 g, 27.5 mmol, 1.0 eq.) in freshly distilled THF (120 mL) was added t-butyllithium (35.6 mL of a 1.7M solution, 2.2 eq.) dropwise via syringe. The reaction was stirred at -78 C for 2h, followed by addition of phenyl disulfide (6.13 g, 28.1 mmol, 1.02 eq) in 20 mL dry THF. The reaction was slowly warmed to r.t. and stirred overnight. Upon completion, 50 mL of sat'd aqueous Na2CO3 was added. The layers were separated and the aqueous layer was extracted with 3 x 20 mL 4:1 hexane/ethyl acetate mix. The organic layers were combined, washed with sat'd. aq. NaCl (1 x 30 mL), dried over MgSO4 and concentrated. Chromatography on silica gel (100% hexanes eluent) provided 2-(phenylthio)toluene (4.85g, 88%) as a colourless oil.
