- Process for Preparing Polysilylalkane
-
Polysilylalkane according to the present invention is represented by following formula. The present invention has an advantage that bis(silyl)alkanes or tri(silyl)alkanes can be manufactured in a high yield by dehydrochlorination with a small amount of catalyst by using a silane compound having a dichloro organic matter or a dichloromethyl group.COPYRIGHT KIPO 2020

According to the present invention, polysilylalkane is represented by chemical formula 3. In chemical formula 3, m is equal to n, and n is equal to zero; and R^3 is a chloromethyl group. In the case of R^4 is H, -SiMe_2Cl, -SiMe_3, -SiMeCl_2, and -SiCl_3, R^3 is equal to -SiCl_3. In the case of R^4 is H, and R^5 is equal to R^6 and R^6 is equal to Me, or R^5 is equal to Me and R^6 is equal to Et, R^3 is -SiCl_3. In the case of R^4 is H, R^5 is equal to -CH_2SiCl_3, and R^6 is Me, R^3 is equal to -SiCl_3. In the case of R^4 is H, R^5 is equal to R^6 and R^6 is equal to -CH_2SiCl_3, R^3 is equal to Et, SiMe_2Cl, -SiMeCl_2, and -SiCl_3, and m is an integer of zero to nine. The manufacturing method is capable of manufacturing bis(silyl)alkane or tri(silyl)alkane in a high yield with a small amount of a catalyst.COPYRIGHT KIPO 2016

- Effect of ether on regioselectivity in hydrosilylation of 1,5-hexadiene with chlorohydrosilanes catalyzed by homogeneous platinum catalysts
-
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. Copyright Taylor & Francis Group, LLC.
