摘要
本文应用Friedel-Crafts反应合成了4种a-二酮:4,4'-双(二甲氨基)苯偶酰(BMB),4,4'-双(二乙氨基)苯偶酰(BEB),4,4'-双(二正丙氨基)苯偶酰(BPB),4,4'-双(二正丁氨基)苯偶酰(BBB),其中BBB为首次合成,BPB文献[1]没有报导物性数据,本文给出了它们的熔点、红外光谱、质谱、H'核磁共振谱.
In our experiments four a-diketones compounds were synthesized through Friedel-Crafts reaction.They are:4,4'-bis(dimethyl amino)benzil(BMB);4,4'-bis(diethylamino) benzil(BEB);4,4'-bis(dipropykmino)benzil(BPB);4,4'-bis(dibutylamino)benzil(BBB).BBB has not been found in previous literatures,and no physical parameters for compound BPB were reported.This at- ticle presents the m,p.,ir,ms and nmr spectra of these four compounds.
