N,N-二取代氨基苯甲醛的合成
Synthesis of N,N-Disubstituted Aminobenzaldehyde
【摘要】 通过N,N-二取代苯胺的酰基化反应,以高收率合成了三种用于制备腙类空穴传输材料的重要中间体,2-甲基-4-(N,N-二苄基)氨基苯甲醛、2-甲基-4-(N-乙基-N-苄基)氨基苯甲醛和4-(N-乙基-N-苄基)氨基苯甲醛,收率分别达99.2%、92.9%和94.8%,高效液相色谱纯度99.2%以上。通过官能团鉴定、紫外吸收光谱、红外吸收光谱、质谱以及元素分析等对产物的组成和结构进行了鉴定。
【Abstract】 Three important intermediates for the preparation of hole transport materials were synthesized by the acylation of N,N-disubstituted aniline.2-Methyl-4-dibenzylaminobenzaldehyde,2-methyl-4-(N-ethyl-N-benzyl) aminobenzaldehyde and 4-(N-ethyl-N-benzyl) aminobenzaldehyde were obtained with the yields of 99.2%,92.9% and 94.8%,respectively.The purity of compounds analysed by HPLC was over 99.2%.The composition and structure of the products were determined by tests of functional group,UV,IR and MS.
