Evidence for the existence of nitrile selenides, potential 1,3‐dipolarophiles in cycloaddition reactions, has been provided by direct spectroscopic methods. The parent nitrile selenide, selenofulminic acid (HCNSe), and its methyl and cyano derivatives have been photolytically generated in an inert solid argon matrix from 1,2,5‐selenadiazoles by 280, 254, and 313 nm UV irradiation, respectively, and
直接分光光度法提供了证据表明存在环化加成反应中潜在的1,3-偶极双亲腈-硒化物。在惰性固体氩气基质中,分别由1,2,5-硒代二唑分别通过280、254和313 nm紫外线辐照光解生成了母体腈硒化物,硒代次膦酸(HCNSe)及其甲基和氰基衍生物,并对其进行了研究。通过紫外光谱和中红外光谱。基态几何结构是通过CCSD(T)/ aug-cc-pVTZ级别的量子化学计算获得的。硒化亚硒化物被认为是线性的,具有相对弱的NSe键。
