41% With 1,10-Phenanthroline; copper(ll) sulfate pentahydrate; potassium carbonate In toluene at 90℃; for 15h; Inert atmosphere; N,N',N''-(benzene-1,3,5-triyltris(ethyne-2,1-diyl))tris(N,4-dimethylbenzenesulfonamide) To a solution of 1,3,5-tris(bromoethynyl)benzene (68 mg; 0.175 mmol) in 1 ml of dried toluene was added 130 mg of N-methyltosylamide (0.704 mmol), 194 mg of K2CO3(1.41 mmol), 17.5 mg of CuSO4*5H2O (0.0704 mmol), and 25 mg of 1,10-phenantroline (0.141 mmol). The flask was fitted with a condenser and put under nitrogen. The mixture was stirred for 15 h at 90°C. The solvent was evaporated and the residue was dissolved in CH2Cl2 and filtered. The filtrate was then concentrated under vacuum and purified by column chromatography (CH2Cl2:cyclohexane 6:4) to givethe trisynamide 6 (50 mg, 0.0714mmol, 41%).

82% With potassium-t-butoxide In <i>tert</i>-butyl alcohol at 35℃; 11.2 General procedure: (2) At a certain temperature, add tBuOK (2.1 mmol), tBuOH (3 mL), (1,1,2-tribromoethyl)benzene (1.0 mmol) into the reaction flask, stir the reaction at 35°C, and a thin layer Chromatography was followed. After the reaction was completed, an appropriate amount of water and ethyl acetate were added, and the mixture was separated and extracted with ethyl acetate. The organic phases were combined, dried over anhydrous sodium sulfate, and the solvent was distilled off under reduced pressure. The residue was separated and purified by column chromatography to obtain (2-bromoethynyl)benzene as a white solid, yield 177 mg, yield 98%.
