analogues of vinyl anions, represents a promising route to extend the conjugation between Si═Si double bonds, previously reported synthetic routes to disilenides involve strongly reducing conditions. Herein, we report a novel synthetic route to disilenides from stable disilenes via the selective cleavage of Si(sp2)–Si(sp3) bonds under milder reaction conditions. Using this method, a 1,4-bis(trimethylsilyl)tetrasila-1
尽管二硅化物,即乙烯基阴离子的二硅类似物的氧化偶联代表了扩展Si═Si双键之间共轭的有前途的途径,但是先前报道的二硅化物的合成途径涉及强烈的还原条件。在本文中,我们报告了在较温和的反应条件下通过选择性裂解Si(sp 2)-Si(sp 3)键从稳定的二硅萘烷中分离出二硅氢化物的新途径。使用该方法,由相应的甲硅烷基取代的二ilene合成了1,4-双(三甲基甲硅烷基)四硅-1,3-二烯(5)。此外,经由四硅-1,3-二烯-1-化物6合成了Et 3 Si-取代的四硅-1,3-二烯7。,这是官能化的四硅1,3-二烯的第一个实例。
