Hydrosilylation of 1,5-hexadiene with chlorohydrosilanes catalyzed by homogeneous platinum catalyst to produce 5-hexenylchlorosilanes was studied. The presence of ether additives was highly effective in improving the regioselectivity and the yield. The formation of a double-bond rearrangement isomer, cis-, or trans-4-hexenylchlorosilanes, during the hydrosilylation was reduced drastically, as well
研究了在均相铂催化剂的催化下,1,5-己二烯与氯氢硅烷发生氢化硅烷化反应生成 5-己烯基氯硅烷。醚添加剂的存在对提高区域选择性和产率非常有效。在氢化硅烷化过程中,双键重排异构体顺式或反式 4-己烯基氯硅烷的形成也急剧减少。
