摘 要:以2,3',4',5'-四氟-4-溴聯(lián)苯和4-丙基苯硼酸為原料,通過(guò)鈴木偶聯(lián)反應合成3',3'',4'',5''-四氟-4-丙基對三聯(lián)苯,優(yōu)化條件下純度99.992%(GC),收率92.3%,目標化合物結構經(jīng)1H NMR表征確證。工藝以咪唑類(lèi)離子液體為溶劑,降低了2,3',4',5'-四氟-4-溴聯(lián)苯自偶聯(lián)產(chǎn)物和脫氟產(chǎn)物的生成,溶劑用量減少,工藝簡(jiǎn)化且綠色環(huán)保,適合工業(yè)化生產(chǎn)。 |
關(guān)鍵詞:鈴木偶聯(lián);離子液體;綠色環(huán)保 |

Abstract:An efficient way for the synthesis of 3',3'',4'',5''-tetrafluoro-4-propyl-triphenyl by using 2,3',4',5'-tetrafluoro-4-bromobiphenyl and 4-propyl phenylboronic acid as raw materials through Suzuki coupling reaction has been designed, moreover, the advantages for using imidazoles ionic liquids in the synthetic method were described, a purity of 99.992% (GC) and a yield of 92.3% was achieved for the target product. The structure of the target compound was characterized by 1H NMR. Using imidazole ionic liquid as solvent was the breakthrough points in this preparation process including effectively reducing the 2,3',4',5'-tetrafluoride-4-bromobiphenyl self-coupling products, and the generation of defluorinated products, effectively reducing the conventional solvent dosage, the green environmental protection and simplified process, and suitable for industrial production. |
Key words:Suzuki coupling; ionic liquid; green environmental protection |
