摘　　要：2,6-二(4-氯甲基苯基)苯并[1,2-d;5,4-d′]二噁唑是含有两个苄基氯的双官能团芳杂环化合物,是合成聚对苯乙炔类发光材料的重要中间体。分别以对甲基苯甲酸和对氯甲基苯甲酸以及对氰基氯苄为主要原料,与4,6-二氨基间苯二酚盐酸盐进行环合反应,合成了2,6-二(4-氯甲基苯基)苯并[1,2-d;5,4-d′]二噁唑,并采用IR,1H NMR和元素分析等分析方法对产物结构进行了确认。同时研究了各步操作对其收率与产物纯度的影响。2,6-Bis （4-chloromethylphenyl） benzo[ 1,2-d ; 5,4-d＇ ] dioxazole is a hetero-cyclic aromatic compound with two benzylchloride groups, and it is used as the key intermediate to prepare PPV light-emitting materials. In this paper, the title compound was synthesized through cyclization reaction of p-methylbenzoic acid, p-chloromethylbenzoic acid and p-nitrilbenzyl chloride with 4,6- diaminoresorcinol dihydrochloride. Its chemical structure was determined by IR, ^1H NMR and element analysis. The yield and purity of the synthesized products were also investigated.
