Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 7051-16-3, name is 1-Chloro-3,5-dimethoxybenzene, A new synthetic method of this compound is introduced below., Computed Properties of C8H9ClO2

General procedure: Cross-Coupling of ortho-, meta-, and para-Substituted, Electron-Rich and Electron-Deficient Aryl Halides and Aryl Mesylates with Aryl Neopentylglycolboronates Catalyzed by NiIICl(1-naph-thyl)(PCy3)2/PCy3 in Anhydrous THF at 23 C; General Procedure 2In an oven-dried test tube charged with a Teflon coated stirring barwere added aryl halide or aryl mesylate (0.3 mmol), aryl neopentyl-glycolboronates (0.315 mmol), K3PO4(H2O)3.2 (191.00 ¡À 1.00 mg, 0.9mmol), and NiIICl(1-naphthyl)(PCy3)2 (11.73 ¡À 0.0510 mg, 0.015mmol, 5% catalyst loading). The test tube was brought into a N2 filledglove box (moisture level <2 ppm) through three degassing cycles andPCy3 (8.4 mg, 0.03 mmol, 10% loading) ligand was added. Distilled sol-vent (1 mL) was added inside the glove box and the test tube wassealed by a rubber septum and left stirring at 23 C. A sample was tak-en by syringe and transferred outside the glove box. The sample wasdiluted by distilled THF (0.2 mL) and filtered through a short columnof Al2O3. The filtrate was concentrated and the GC analysis was car-ried out. The reaction mixture was diluted with CH2Cl2 (2 mL), filteredthrough a layer of Al2O3, and washed with CH2Cl2 (3 1 mL). The fil-trate was collected and concentrated under vacuum. The crude prod-uct was purified by column chromatography on silica gel with EtO-Ac/hexane mixture as eluent. The reductive elimination side-productwas also isolated and characterized. The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future. Reference:

Application of 7051-16-3, A common heterocyclic compound, 7051-16-3, name is 1-Chloro-3,5-dimethoxybenzene, molecular formula is C8H9ClO2, 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.

REFERENCE EXAMPLE 68 5-Chloro-1,3-Dihydroxybenzene A solution 5-chloro-1,3-dimethoxybenzene (20.71 g) in dichloromethane (50 ml) at -78 C. was treated dropwise with a solution of boron tribromide (56 ml) in dichloromethane (250 ml), maintaining the temperature at -78 C. The mixture was slowly warmed to room temperature then left at ambient temperature for 48 hours. The reaction mixture was quenched with water (100 ml), (sodium hydroxide scrubber required) and partitioned between water (1000 ml) and dichloromethane (1000 ml). The organic layer was separated and the aqueous layer was extracted twice with a mixture of dichlioromethane and methanol (500 min, 98:2, v/v). The combined organic extracts were washed with saturated brine (200 ml), dried over magnesium sulphate and evaporated affording the title compound (10.17 g) as a yellow/orange oil which was used without further purification.

The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
