摘要
通过Claisen缩合反应,在强碱叔丁醇钾的作用下,把长链端烯引入到β-二酮分子中,合成了一种新型的含长链端烯的β-二酮化合物——13-十四碳烯-2,4-二酮(BSH),并通过红外光谱、核磁共振、质谱和元素分析对其结构进行了确证。这种β-二酮化合物在氯仿溶液中主要以烯醇形式存在。该化合物可作为配体用于有机电致发光配合物的合成。
A new β-diketone compound with a long chain end-alkene, tetradec-13-ene-2,4-dione （BSH） was synthesized from methyl ketone and ester by classical Claisen condensation using （CH3 ）3COK as strong base. Its structure was confirmed by IR, ^1H NMR, Mass spectra. The results show that the new β-diketone compound exists in the Chloroform in chloroform solvent. It can be used in the synthesis of coordination compounds for organic light-emitting materials.
