Application of 14862-52-3, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 14862-52-3, name is 3,5-Dibromochlorobenzene belongs to chlorides-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.
To a stirred solution of 1,3-dibromo-5-chlorobenzene (800 mg, 2.96 mmol) and 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridine (600 mg, 2.96 mmol) in 1,4-dioaxane (15 mL) K2CO3 (1.2 g, 8.80 mmol) was added and the mixture was degassed with argon for 20 minutes. Pd (PPh3)4 (102 mg, 0.08 mmol) was added to reaction mixture and degassed for another 20 minutes. The reaction mixture was refluxed under stirring for 8 hours and then filtered through celite pad. The filtrate was concentrated and the residue was purified by column chromatography on silica (100-200 mesh) eluting with 15% ethyl acetate in petroleum ether to afford the title compound as white solid (400 mg, 50 %). 1H NMR: (300 MHz, CDCl3) delta 8.70 (dd, J = 4.5, 1.5 Hz, 2H), 7.65-7.64 (m, 1H), 7.59-7.58 (m, 1H), 7.54-7.53 (m, 1H), 7.45 (dd, J = 4.2, 1.5 Hz, 2H); ESIMS: m/z = 268.0 [(M+H)+].
The synthetic route of 3,5-Dibromochlorobenzene has been constantly updated, and we look forward to future research findings.
