Electric Literature of 610-96-8, These common heterocyclic compound, 610-96-8, name is Methyl 2-chlorobenzoate, 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: 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 synthetic route of 610-96-8 has been constantly updated, and we look forward to future research findings.
