The electrogeneration of diorganylsilanones from difunctional precursors Y(CH2)3(Me)SiX2 and Ph2SiX2
(Y = NH2, CF3, CN; X = Cl, OEt, OMe), performed in the presence of hexamethyldisiloxane or hexamethylcyclotrisiloxane (D3) in the ionic liquids [C5H5NC8F18]·NTf2, [C5H5NC18H38]·NTf2 and Me3BuN·NTf2, which reveal high solubility of oxygen and are inert toward superoxide anion, allows functionalized siloxanes to be produced selectively in good isolated yields.
双功能前体 Y(CH2)3(Me)SiX2 和 Ph2SiX2 电生成二有机基硅烷
(Y = NH2、CF3、CN;X = Cl、OEt、OMe),在六甲基二硅氧烷或六甲基环三硅氧烷(D3)存在下,在离子液体 [C5H5NC8F18]·NTf2、[C5H5NC18H38]·NTf2 和 Me3BuN·NTf2 中进行,其中显示出氧的高溶解度并且对超氧阴离子呈惰性,允许以良好的分离产率选择性地生产官能化硅氧烷。
