两个新型联吡啶类化合物的合成以及表征

Synthesis and characterization of two novel bypyridine complexes

我们利用固相合成法,氢氧化钠存在的情况下,分别研磨4-乙酰吡啶和对甲基苯甲醛,对甲基苯乙酮和4-吡啶甲醛,然后再利用醋酸铵合环,高锰酸钾氧化,分别得到了两个新型刚性配体名称4’-(4-羧苯基)-2,4’︰6’,4"-三联吡啶(L1)和2,6-二(4-羧苯基)-4,4’-二联吡啶(L2),产率分别为:35.8%;73.2%。

Using solid-state reaction,we ground 4-acetylpyridine and p-tolualdehyde or pyridine-4-carboxaldehyde and 4-methylacetophenone in the presence of excess sodium hydroxide,respectively.Then ammonium acetate and potassium permanganate were used for pyridine ring closed and oxidation,two rigid ligands 4＇-（4-carboxyphenyl）-2,4＇︰6＇,4＂-terpyridine（L1） and 2,6-di-p-carboxyphenyl-4,4＇-bipyridine（L2） were obtained,the yields are 35.8 % and 73.2 % respectively.
