Related Products of 4028-63-1,Some common heterocyclic compound, 4028-63-1, name is 2,4,6-Trimethyliodobenzene, molecular formula is C9H11I, 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.
in room temperature,A mixture of 2,4,6-trimethyliodobenzene (1.2 mmol, 3 equiv)Elemental selenium (1.2 mmol, 3 equiv),5-phenyl-1,3,4-oxadiazole (0.4 mmol, 1 equiv),Cu (OAc) 2 (0.04 mmol),Potassium carbonate (1.2 mmol, 3 equiv) was added to the reaction tube,Then filled with nitrogen, and replaced three times, in the nitrogen reaction environment,Then, 2 mL of DMF was added to the reaction solvent and stirred at 140 ° C for 24 h.After the reaction was monitored by thin layer chromatography, the reaction mixture was cooled,Then diluted with ethyl acetate, and the diluted solution was transferred to a separatory funnel,Extracted with saturated brine, separated from the aqueous phase and organic phase, and then extracted with ethyl acetate 3 times,The organic phases were combined, 5 g of anhydrous sodium sulfate was added,Wash the filter cake with 5 mL of ethyl acetate each time 3 times, then spin off the solvent,The product was isolated by column chromatography (eluent: petroleum ether: ether = 98: 2)The product was a yellow solid, yield 90percent, product weight 123 mg.
The synthetic route of 4028-63-1 has been constantly updated, and we look forward to future research findings.
