By pyrolysis of various polymethylene bridged benzimidazolyl azides in a mixture of polyphosphoric and acetic acid examples of the new ring system of imidazo[4,5-g]benzoxazole were obtained. Aspects of their ultraviolet and n.m.r. spectra are discussed.
通过在多磷酸和乙酸的混合物中热解各种多亚甲基桥连的苯并咪唑基叠氮化物,获得了咪唑并[4,5- g ]苯并恶唑新环系统的实例。他们的紫外线和核磁共振谱方面进行了讨论。
