100125-12-0, 3,8-Dibromo-1,10-phenanthroline is a catalyst-ligand compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

General procedure: The compound TP was prepared by a palladium-catalyzed cross-coupling reaction from 3-bromo-1,10- phenanthroline. First, 3-bromo-1,10-phenanthroline (2.6 g, 10 m ml) in methylbenzene (80 m ml) was stirred in N2 atmosphere. Second, Na2CO3 solution (10 ml, 20 m mol), the mixtures of thiophen-3-yl-3-boronic acid (1.54 g, 12 m mol), methylbenzene (50 m ml) and ethanol (5 ml) were carefully added in turn. Then, the new suspension was left to react for 12 h at 80 C by constant refluxing. The reaction mixture was rotating-evaporated, and was then purified by dissolving with CH2Cl2, water washing, drying with Na2SO4, filtration, concentration and column chromatography (silica gel, CHCl3). Finally, the white solid product (yield, 85%) was obtained after drying in vacuo.

100125-12-0, 100125-12-0 3,8-Dibromo-1,10-phenanthroline 10991348, acatalyst-ligand compound, is more and more widely used in various.

100125-12-0, 3,8-Dibromo-1,10-phenanthroline is a catalyst-ligand compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

To a three-necked flask of 500 ml, 1.0 g (2.96 mmol) of 3, 8-dibromo-1, 10-phenanthroline [6] [*2),] 2.9 g (11.8 mmol) of fluorantene-8-boronic acid [7], 140 ml of toluene and 70 ml of ethanol were charged and an aqueous solution of 12 g of sodium carbonate/60 ml of water was dropped under stirring at room temperature in a nitrogen atmosphere, and then 0.17 g (0.15 mmol) of tetrakis (triphenylphosphine) palladium (0) was added. After stirring at room temperature for 30 minutes, the mixture was raised to a temperature of [77C] and stirred for 3 hours. After the reaction, the organic layer was extracted with chloroform and dried with anhydrous sodium sulfate, and then purified with an alumina column (hexane/chloroform solvent mixture developer), obtaining 1.4 g (yield of [82%)] of Exemplary Compound No. 8 (yellow crystal).

As the paragraph descriping shows that 100125-12-0 is playing an increasingly important role.
