Reaction of dimethylsulfoxonium methylide with a β-silylmethylene malonate gives diversified products, cyclopropane, cyclobutane or allyl and homoallyl silanes depending upon the stoichiometry of the reactants and reaction conditions. Contrary to this, reaction of a β-arylmethylene malonate gives only the cyclopropane product. The product(s) formed are unique and the silicon group played a crucial
取决于反应物的化学计量和反应条件,二甲基亚砜基亚甲基与β-甲硅烷基丙二酸丙二酸酯的反应产生了多种产物,环丙烷,环丁烷或烯丙基和均烯丙基硅烷。与此相反,β-芳基亚甲基丙二酸酯的反应仅产生环丙烷产物。所形成的产品是独特的,并且硅基团通过协助和/或参与该过程而发挥了至关重要的作用。
