Difunctional disilanes of the general type XR2SiSiR2X (1–5) (X = OMe, H; R = Me, Ph, H) have been synthesized by electrolysis of the appropriate chlorosilanes XR2SiCl in an undivided cell with a constant current supply and in the absence of any complexing agent. Reduction potentials of the chlorosilane starting materials derived from cyclic voltammetry measurements were used to rationalize the results
通用类型XR 2 SiSiR 2 X(1-5)(X = OMe,H; R = Me,Ph,H)的双官能乙硅烷是通过在恒定的不分隔电池中电解合适的氯硅烷XR 2 SiCl合成的在没有任何络合剂的情况下供电。由循环伏安法测量得出的氯硅烷原料的还原电位用于合理化制备性电解的结果。通式的MeO(ME的有机官能硅烷2)的SiC 6 H ^ 4 Y(图6a - Ç,7)随后通过反应得到的符号-对二甲氧基四甲基乙硅烷(1)在对位芳基溴化物BrC 6 H 4 Y(Y = OMe,NEt 2,NH 2)存在下具有NaOMe 。
