摘 要:以2-溴-5-硝基噻吩(BNT)和5-甲;-2-噻吩硼酸(FTBA)為原料,通過(guò)Suzuki偶聯(lián)反應合成了5'-硝基-[2,2'-聯(lián)噻吩]-5-甲醛,考察了堿、溶劑、催化劑及加料順序對該Suzuki偶聯(lián)反應的影響。結果顯示:優(yōu)化條件為以1,2-二甲氧基乙烷(DME)為溶劑,氟化鈉為堿,Pd/C為催化劑,一鍋加料。 |

Abstract:5'-Nitro-[2,2'-bithiophene]-5-carbaldehyde was synthesized via Suzuki coupling reaction using 5-nitro-2-bromothiophene and 5-formyl-2-thiopheneboronic acid as the starting materials. The influences of various bases,solvents,catalysts and addition sequence of materials on the coupling reaction were investigated. The results showed that the optimum reaction conditions were using DME as the solvent,NaF as the base,Pd/C as the catalyst and all were in one-pot. |
