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

Provided is an organic chlorohydrosilane, a useful starting material for preparing silicon polymers and a method for preparing the same. More particularly, the present invention enables the synthesis of various novel organic chlorohydrosilanes in high yield by an exchange reaction between an Si—H bond of a chlorosilane which can be obtained in an inexpensive and easy manner and an Si—Cl bond of an another organic chlorosilane using a quaternary organic phosphonium salt compound as a catalyst. Since the catalyst can be recovered after its use and reused, the present invention is very economical and thus effective for mass-producing silicon raw materials.
