摘要:
本发明涉及一种逐步合成在硅原子上带有最多四种不同有机基团取代的硅氢化物的过程,其中该过程包括至少以下步骤:a) 通过重分配反应、使用醚/HCI试剂对氢硅烷进行选择性氯化,或者通过使用四氯化硅对氢硅烷进行选择性氯化来制备双功能氢氯硅烷;至少一个步骤 b) 将双功能氢氯单硅烷进行氢硅化反应;至少一个步骤 c) 对氯代单硅烷进行氢化;以及步骤 d) 在氢硅化反应中获得硅氢化物化合物。

hydrosilation on addition of MeCl/sub 2/SiH or 1-heptene, respectively.more » The kinetic behavior of the supported catalyst differs from soluble hydrosilation catalysts in its sensitivity toward oxygen, lack of an induction period, and inhibition by coordinating solvents or excess olefin. Addition of Hg, a poison for metallic platinum, to catalysis solutions did not alter the catalytic rate. Thermal activation
