摘要:"有机硅"在自然界中并不存在,但现代化学很难想象没有硅与碳结合的情况.虽然含硅商品化学品(例如通过"直接工艺" 1,2,3,4产生的那些)看起来很简单,但选择性制备芳基取代和烷基取代(官能化)硅化合物(称为硅烷)并非易事.氯硅烷如 Me 4− N Sicl N ( N = 1-3) 以及 Sicl 4 ( N = 4) 是合成含硅分子的常见起点.然而这些方法常常遇到具有挑战性的分离问题5 .相反,具有四个烷基的硅烷被认为是合成的死角.在这里,我们介绍了芳烃离子催化的卤代脱烷基化反应,可有效地将 Me 4 Si 和相关的季硅烷转化为各种官能化衍生物.该反应使用烷基卤和芳烃(共)溶剂:烷基卤是卤化物源,最终与芳烃进行弗里德尔-克来福特烷基化以再生催化剂6,而芳烃离子则充当强布朗斯台德酸原脱烷基化步骤7 .例如,在硅药物前体的合成中,证明了自上而下的卤代烷基化方法相对于报道的自下而上程序的优势.此外,连接到烷基链上的相当惰性的me

摘要:The process for cleaving the heavy by-products derived from the synthesis of alkylchlorosilanes, in particular C1 to C6 alkylchlorosilanes, more particularly methylchlorosilanes, in particular for the cleavage of alkylchlorodisilanes, in particular methylchlorodisilanes having from one to five chlorine atoms, is carried out by treatment with hydrochloric acid in the presence of a catalytic system which comprises at least one metal phosphate, preferably associated with a basic impregnation compound. The metal phosphate may in particular correspond to the formula: M(XPO4)y in which M represents a metal chosen from: monovalent metals, in which case X is 2H and y=1 divalent metals, in which case X is H and y=1 trivalent metals, in which case X is absent and y=1 tetravalent metals, in which case X is: H and y=2 pentavalent metals, in which case X is 0 and y=1.

摘要:1,2 Dichloro-1,1,2,2-tetramethyldisilane is synthesized in high yield and good purity starting from a crude mixture of chloromethyldisilanes formed as by-products in the manufacture of silicones. The new method uses less than half as much Grignard reagent as previous methods required. The synthesis can also be used to produce other haloalkyldisilanes such as chloropentamethyldisilane or 1,1,2 trichloro-1,2,2-trimethyldisilane.

摘要:A process for the preparation of dimethyldichlorosilane from the low-boiling and high-boiling by-products of the direct synthesis of methylchlorosilane, comprising reacting methyltrichlorosilane simultaneously with the low-boiling components having a high content of methyl groups and with the high-boiling non-cleavable components, in the presence of a catalyst, at a temperature between about 250° C. and 400° C. and under a pressure of up to 100 bar.
