either azolyltrienes in a Wittig reaction, or to undergo cyclization to a dihydrobenzene containing the azole substituent. Transformation with an aza-Wittig reagent gave tetrazolylpyridines. The ambident reactivity was found to be dependent on the substituent of the phosphorane, which was rationalized by ab initio (DFT) calculation of the atomic charges of the reaction centres.
发现偶氮烯丙基丙烯醛与带有共轭双键的磷烷的反应在维蒂希反应中产生偶氮烯丙基,或环化成含唑取代基的二氢苯。用氮杂-维蒂希试剂转化得到四唑基吡啶。发现周围的反应性取决于磷烷的取代基,这是通过对反应中心原子电荷的从头算(DFT)计算来合理化的。
