These common heterocyclic compound, 106-39-8, name is 1-Bromo-4-chlorobenzene, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route. Recommanded Product: 1-Bromo-4-chlorobenzene
General procedure: To an oven dried 5 mL microwave vessel was addedPd(dppf)Cl2·CH2Cl2 (4 mol%), halide/pseudohalide (1 equiv),boron coupling partner (1 equiv), and Cs2CO3 (3 equiv). Thevessel was then capped and purged with N2 before addition ofCyrene (1 mL, 0.25 M) and H2O (1.8 mL). The reaction mixturewas heated to 50 C and maintained at this temperature withstirring for 5 h before the vessel was vented and decapped. Thesolution was then diluted with Et2O (10 mL) and washed withwater (2 × 20 mL) and brine (2 × 20 mL). The organics were thenpassed through a hydrophobic frit and concentrated underreduced pressure to give a residue, which was purified by flashchromatography (silica gel) to afford the title compound.
The synthetic route of 1-Bromo-4-chlorobenzene has been constantly updated, and we look forward to future research findings.
