o-Nitrophenols and o-nitroaniline were reacted with amines at 210-215°C to produce the corresponding benzoxazoles and benzimidazoles, respectively, in moderate yields. The reactions between o-nitrophenols containing a CO 2 Me or OMe group on their benzene rings and N,N-diethylaniline were examined to investigate the effects of the position and electronic character of these substituents on the formation
邻硝基苯酚和邻硝基苯胺在 210-215°C 与胺反应,分别以中等收率产生相应的苯并恶唑和苯并咪唑。研究了苯环上含有CO 2 Me 或OMe 基团的邻硝基苯酚与N,N-二乙基苯胺之间的反应,以研究这些取代基的位置和电子特性对恶唑环形成的影响。
