1,3,5-TRIETHYNYLBENZENE Use and Manufacturing
(9) A (1 g, 2.73 mmol) and K2CO3 (1.24 g, 8.99 mmol) were dissolved in 100 mL CHCl3/MeOH 3:2 and stirred at rt for 24 h. The solvent was removed on a rotary evaporator and the off-white solid was purified by silica gel column chromatography using dichloromethane/hexane 1:4 to give the product. Isolated yield: 350 mg. 1H NMR (CDCl3, 400 MHz): (ppm) 7.57 (s, 3H, H1), 3.11 (s, 3H, H2). 13C{1H} NMR (CDCl3, 100 MHz): (ppm) 136.12, 132.48, 123.38, 123.01, 83.51, 82.10, 70.59, 79.19.General procedure: The procedure was modified following the Sonogashira coupling protocol. 1, 3, 5-Tribromobenzene (31.5 g, 100 mmol) was dissolved in dry triethylamine (250 mL) under an atmosphere of nitrogen. Copper(I) iodide (191 mg, 1.0 mmol), dichlorobis(dibenzonitrile)palladium(II) (192 mg, 0.5 mmol) were added to the stirred solution. 2.2.2 1, 3, 5-Triethynylbenzene 2 [15]A solution of 3 (6.54 g, 19.62 mmol) in toluene (100 mL) was heated up to boiling.Powdered potassium hydroxide (3.30 g, 58.86 mmol) was added and the mixture refluxed for 5 h. After cooling down to room temperature, diethyl ether (50 mL) was added. The organic phase was washed with water (2 * 100 mL)
1,3,5-Triethynylbenzene is used as the carbon precursor for graphene synthesis on rhodium. It is also used as a connecting unit for various transition metal building blocks.
