2-Phenyl-5-oxazolone (hippuric acid azlactone, I) gives good yields of benzoylamino-ketones(II) in the Friedel-Crafts benzoylaminoacetylation of aromatic hydrocarbons. On this basis a new synthesis of 2,5-diaryloxazoles was devised, resulting in the simplest preparation of several 2-phenyl-5-aryl-oxazoles (III), which are good scintillator solutes. Ultra-violet absorption spectra are described and discussed
在芳烃的弗里德-克来夫(Friedel-Crafts)苯甲酰氨基乙酰化反应中,2-Phenyl-5-oxazolone(hippuric acid azlactone,I)得到良好的苯甲酰氨基酮(II)收率。在此基础上,设计了新的2,5-二芳基恶唑合成方法,从而最简单地制备了几种2-苯基-5-芳基恶唑(III),它们是良好的闪烁体溶质。描述并讨论了紫外线吸收光谱。
