Yield	Reaction Conditions	Operation in experiment
	With 3-chloro-benzenecarboperoxoic acid; In dichloromethane; at 20℃;	General procedure: To a solution of (4-bromo-3-chlorophenyl)(ethyl)sulfane (0.870 g, 3.5 mmol) in DCM (8 mL) was added 70.0% m-chloroperoxybenzoic acid (2.131 g, 8.6 mmol). The reaction mixture was stirred at room temperature overnight. The solid was filtered off, and the filtrate was concentrated to afford product as a white solid, which was used without further purification (1.2 g, 87%). NMR (300 MHz, CDCb): delta 7.98 (d, J= 2.1Hz, 1H), 7.84 (d, J= 8.5 Hz, 1H), 7.64 (dd, J= 8.5, 2.1Hz, 1H), 3.14 (q, J = 7.5 Hz, 2H), 1.31 (t, J = 7.5 Hz, 3H).

Yield	Reaction Conditions	Operation in experiment
		General procedure: To a solution of l-bromo-4-(isopropylsulfonyl)benzene (100 mg, 0.38 mmol) in dry THF (2 mL) was slowly added LDA (0.19 mL, 0.38 mmol, 2.9 M in THF/heptane/ethylbenzene) at -78C. After 1.5 hours, iodoethane (91 mu,, 1.1 mmol) was added and the mixture was allowed to warm up to room temperature overnight. The mixture was diluted with saturated aqueous ammonium chloride, extracted with ethyl acatate (x 3), and the combined organic layers were dried over Na2S04, filtered and concentrated in vacuo. The residue was purified by silica chromatography, eluting with 0-40% ethyl acetate/hexanes to afford intermediate 1-14-1 as a solid. 1H NMR (600 MHz, CDC13): delta 7.71 (d, / = 8.8 Hz, 2H), 7.67 (d, / = 8.2 Hz, 2H), 1.71 (q, / = 7.6 Hz, 2H), 1.25 (s, 6H), 0.93 (t, / = 7.6 Hz, 3H).
