METHOD FOR PREPARATION OF ORGANOSILICON COMPOUND HAVING ACRYLOYLOXY GROUP OR (METH)ACRYLOYLOXY GROUP

To provide a method for preparing an organosilicon compound having a (meth)acryloyloxy group, which can suppress the growth reaction of a (meth)acrylate compound.SOLUTION: The present disclosure provides a method for preparing an organosilicon compound of formula (3) by simultaneously feeding a compound of formula (1) and a compound of formula (2) in the presence of a polymerization inhibitor and effecting a hydrosilylation reaction in the presence of a platinum catalyst. The content of the compound of formula (2) is 0-100 mol% based on the content of the organosilicon compound of formula (3) in the reaction system (where, R1 is an optionally substituted C1-C10 monovalent hydrocarbon group, X is a halogen atom, n is an integer of 1-3, R2 is H or a methyl group, and R3 is an unsubstituted C1-C18 alkylene group).SELECTED DRAWING: None 【課題】（メタ）アクリレート化合物の成長反応を抑えることができる、（メタ）アクリロイルオキシ基を有する有機ケイ素化合物の製造方法の提供。【解決手段】重合禁止剤の存在下、式（１）で示される化合物と、式（２）で示される化合物とを同時に供給し、白金触媒を用いてヒドロシリル化反応させて、式（３）で示される有機ケイ素化合物を製造する方法であって、反応系中における式（２）で示される化合物の含有量が、式（３）で示される有機ケイ素化合物の含有量に対して０〜１００モル％となるように反応する製造方法。（式中、Ｒ1は置換または非置換の炭素数１〜１０の１価炭化水素基；Ｘはハロゲン原子；ｎは１〜３の整数；Ｒ2はＨまたはメチル基；Ｒ3は非置換の炭素数１〜１８のアルキレン基を表す。）【選択図】なし
