YieldReaction ConditionsOperation in experiment
48% With 1,1'-bis-(diphenylphosphino)ferrocene; (1,1'-bis(diphenylphosphino)ferrocene)palladium(II) dichloride; potassium acetate In 1,4-dioxane at 80℃; for 12 h; Inert atmosphere [0832] A mixture of 4-(trifluoromethyl)cyclohex- i-en-i -yltrifluoromethanesulfonate (2.24 g, 7.50 mmol, 1.00 equiv), 4,4,5 ,5-tetramethyl-2-(tetramethyl- 1,3 ,2-dioxaborolan-2-yl)- 1,3 ,2-dioxaborolane (2.86 g, 11.26 mmol, 1.50 equiv), Pd(dppf)C12 (160 mg, 0.22 mmol, 0.O3equiv), dppf (125 mg, 0.23 mmol, 0.03 equiv), and KOAc (2.2 g, 22.42 mmol, 2.99 equiv) in dioxane (50 mL) was stirred for 12 h at 80°C under nitrogen. The resulting mixture was concentrated under vacuum. The residue was purified by a silica gel colunm eluting with ethyl acetate/petroleum ether (1/20) to afford the title compound (1 g, 48percent) as a white solid. LCMS [M+H] 277. ‘HNMR(300 MHz, CDC13) 6.53 (s, 1H), 2.37 - 1.98 (m, 7H), 1.26 (m, 12H).
2.6 g With 1,1'-bis-(diphenylphosphino)ferrocene; (1,1'-bis(diphenylphosphino)ferrocene)palladium(II) dichloride; potassium acetate In 1,4-dioxane at 80℃; Inert atmosphere 4,4,5,5-tetramethyl-2-(4-(trifluoromethyl)cyclohex- 1-enyl)-1,3,2-dioxaborolane. A mixture of 4- (trifluoromethyl)cyclohex- 1-en-i -yl trifluoromethanesulfonate (3.636 g, 12.19 mmol, 1.00 equiv), 4,4,5 ,5-tetramethyl-2-(tetramethyl- 1,3 ,2-dioxaborolan-2-yl)- 1,3 ,2-dioxaborolane (3.626 g, 14.28 mmol, 1.17 equiv), KOAc (3.892 g, 39.66 mmol, 3.25 equiv), Pd(dppf)C12 (398 mg, 0.54 mmol, 0.03 equiv), dppf (203 mg, 0.37 mmol, 0.03 equiv) in 1,4-dioxane (60 mL) was stirred under nitrogen overnight at 80°C. The reaction mixture was allowed to cool to room temperature. The reaction mixture was concentrated under reduced pressure. The residue was partitioned between ethyl acetate (50 mL) and water (50 mL), phases were separated. The aqueous phase was extracted with ethyl acetate (2x50 mL). The combined extracts were washed with water (50 mL), dried over anhydrous sodium sulfate and concentrated under reduced pressure. The residue was purified by flash chromatography on silica gel with ethyl acetate : petroleum ether (1:10) to afford the title compound (2.6 g) as a white solid. GCMS: 276.
