| titleOfInvention | 1,2-bis (9,9-dibutylfluoren-2-yl) benzo [1,2-j] coronene and the method of its preparation |
| abstract | The subject of the invention is 1,2-bis (9,9-dibutylfluoren-2-yl) benzo [1,2-j] coronene represented by the formula 1. The invention is also related to the method of obtaining 1,2-bis (9,9-dibutylfluorine). 2-yl-benzo [1,2-j] coronene represented by formula 1, which consists in introducing 1,2-bis (9,9-dibutylfluoren-2-yl) benzo [gh] perylene, a mixture of molten succinonitrile with 1,2-dimethoxyethane in a volume ratio of 3: 1 to 1: 3, in an amount of 5 to 20 ml per 1 mmol of 1,2-bis (9,9-dibutylfluoren-2-yl) benzo [ghi] perylene , and a reagent generating aryn in the form of cesium fluoride in an amount of 2 to 8 mmol per 1 mmol of 1,2-bis (9,9-dibutylfluoren-2-yl) benzo [gh] perylene, and then the precursor is added, preferably dropwise gasoline in the form of 2-trimethylsilylphenyl triflate in an amount of 2 to 8 mmoles per 1 mmole of 1,2-bis (9,9-dibutylfluoren-2-yl) benzo [gh] perylene, at a rate of not more than 20 mmoles per minute, the reactor contents are stirred at a temperature of 40 to 100 ° C under an atmosphere of ga indifferently for at least 12 hours. Preferably, after completion of the cycloaddition reaction, the contents of the reactor are cooled to a temperature of not less than 50 ° C, preferably to ambient temperature, and volatile fractions are evaporated, and the residue is washed several times with liquid, saturated aliphatic hydrocarbon, then several times with water and finally several times with times with low boiling ether to give the final product 1,2-bis (9,9-dibutylfluoren-2-yl) benzo [1,2-j] coronene,> 97% purity (NMR) as a yellow solid, yield up to 55%. |
