corresponding 2-(azidomethyl)allylsilane was prepared through reaction with NaN 3 . The product was stable upon isolation and storage and could be used for thermal cycloaddition of the azido group with alkenes to give allylsilane-containing triazolines or aziridines. This reaction was not accelerated by microwave (MW) dielectric heating, however, the azide fragment undergoes MW-assisted Cu(I)-catalyzed cycloaddition
以市售的2-(氯甲基)-烯丙基三甲基硅烷为原料,通过与NaN 3 反应制备相应的2-(叠氮甲基)烯丙基硅烷。产物在分离和储存时稳定,可用于叠氮基与烯烃的热环加成反应,得到含烯丙基硅烷的三唑啉或氮丙啶。微波 (MW) 介电加热不会加速该反应,但是,叠氮化物片段会与一系列炔烃(包括炔酰胺)发生 MW 辅助的 Cu(I) 催化的环加成反应。路易斯酸介导的烯丙基硅烷与醛的 Hosomi-Sakurai 反应也是可能的。
