Electric Literature of 108-70-3, These common heterocyclic compound, 108-70-3, name is 1,3,5-Trichlorobenzene, 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.
General procedure: An oven-dried and argon-flushed pressure tube was charged with 1,3,5-trichlorobenzene, 1,2,4-trichlorobenzene or 1,2,3-trichlorobenzene (0.25 mmol), Pd2(dba)2 (1.25 mol%), cataCXium A (5.0 mol%), boronic acid (1.5 mmol) and K3PO4 (1.5 mmol) followed by anhydrous toluene (4.0 mL). The tube was sealed with a Teflon valve and the reaction mixture was stirred at 110 C for 24 h. The cooled reaction mixture was diluted with water and extracted with DCM. The combined organic layers were dried (Na2SO4), filtered and the filtrate was concentrated in vacuo. The residue was purified by column chromatography.
Statistics shows that 1,3,5-Trichlorobenzene is playing an increasingly important role. we look forward to future research findings about 108-70-3.
