YieldReaction ConditionsOperation in experiment
86% With N-Bromosuccinimide;dibenzoyl peroxide; In tetrachloromethane; for 20h;Heating / reflux; A mixture of <strong>[452-79-9]3-fluoro-4-iodotoluene</strong> (2.26g, 9.58mmol), N-bromosuccinimide (2.03g, 11.49mmol) and benzoyl peroxide (5mol%, 116mg, 0.48mmol) in carbon tetrachloride (5ml) was stirred at reflux for 20 hours, cooled, diluted with dichloromethane and filtered. The purple coloured filtrate was washed with saturated sodium thiosulphate solution (aq) (20ml). The organic layer was separated, dried over sodium sulphate and the solvent removed by rotary evaporation to give the title compound as a yellow oil (2.58g, 86%).1 H-NMR (250MHz, CDCI3): 4.41 (2H, s), 6.94 (1 H, m), 7.11 (1 H, m), 7.72 (1 H, m).
86% With N-Bromosuccinimide; dibenzoyl peroxide; In tetrachloromethane; for 20h;Reflux; A mixture of <strong>[452-79-9]3-fluoro-4-iodotoluene</strong> (2.26 g, 9.58 mmol), N-bromosuccinimide (2.03 g, 11.49 mmol) and benzoyl peroxide (5 mol %, 116 mg, 0.48 mmol) in carbon tetrachloride (5 ml) was stirred at reflux for 20 hours, cooled, diluted with dichloromethane and filtered. The purple coloured filtrate was washed with saturated sodium thiosulphate solution (aq) (20 ml). The organic layer was separated, dried over sodium sulphate and the solvent removed by rotary evaporation to give the title compound as a yellow oil (2.58 g, 86%).1H-NMR (250 MHz, CDCl3): delta 7.72 (1H, m), 7.11 (1H, m), 6.94 (1H, m), 4.41 (2H, s).
86% With N-Bromosuccinimide; dibenzoyl peroxide; In tetrachloromethane; for 20h;Reflux; N-Bromosuccinimide (2.63g, 14.78mmol) and benzoylperoxide (0.20g, 0.62mmol) were added to a solution of <strong>[452-79-9]3-fluoro-4-iodotoluene</strong> (2.90g, 12.29mmol) in 7mL of tetrachloromethane. The resulting solution was refluxed for 20h. Thereafter, the reaction was allowed to cool to room temperature and was then diluted with 30mL of CH2Cl2. The solid phase was filtered off and the filtrate was washed with 30mL of a saturated solution of sodium thiosulphate. The organic layer was dried over Na2SO4 and evaporated. The crude product was purified by flash chromatography (AcOEt/PE 2:98), giving 3.45g (86%) of 8 as a white solid. Rf=0.76 (AcOEt/PE 5:95); mp=46-48C. 1H NMR (600MHz, CDCl3) delta 7.71 (m, 1H), 7.11 (m, 1H), 6.94 (m, 1H), 4.41 (s, 2H); 13C NMR (150MHz, CDCl3) delta 161.0 (J=246.5Hz), 140.6 (J=7.6Hz), 139.9 (J=1.3Hz), 126.4 (J=3.2Hz), 116.4 (J=24.5Hz), 81.3 (J=25.6Hz), 31.5; 19F (564MHz, CDCl3) delta -92.9 (t, J=7.3Hz). Anal. calcd for C7H5BrFI: C, 26.70; H, 1.60; found: C, 26.70; H, 1.58.
