A pohotoproduct of o-azidobiphenyl in acetonitrile in the presence of tetracyanoethylene (TCNE), analysed by X-ray crystallography and high-resolution n.m.r. spectroscopy, was shown to have the spiro structure corresponding to the nucleophilic addition of 2-azacyclohepta-2,4,6-trienylidene to TCNE.
X射线晶体学和高分辨率NMR光谱分析表明,在四氰基乙烯(TCNE)存在下,邻乙二氮杂联苯的光产物在乙腈中具有对应于2-氮杂环庚二-2,4亲核加成的螺结构,6-三烯基为TCNE。
