Silyl isoxazolines have been synthesized by [2 + 3] cycloaddition reaction of nitrile oxides and silylnitronates to vinyl- and allylsilanes. The direction of the cycloaddition reaction of nitrile oxides to trialkoxyvinylsilanes has been shown to depend on the nature of the substituents on silicon and on the method used to generate the nitrile oxides. The addition of silyl esters of aci-nitromethane
甲硅烷基异恶唑啉是通过腈氧化物和甲硅烷基亚硝酸盐的[2 + 3]环加成反应合成乙烯基硅烷和烯丙基硅烷而合成的。已显示腈氧化物与三烷氧基乙烯基硅烷的环加成反应的方向取决于硅上取代基的性质以及用于产生腈氧化物的方法。将三硝基硝基甲烷的甲硅烷基酯加到三乙氧基乙烯基硅烷中,得到5-甲硅烷基和4-甲硅烷基异构体。讨论了甲硅烷基异恶唑啉的结构。
