Title:
METHOD FOR PRODUCING ORGANOSILICON COMPOUND HAVING (METH)ACRYLOXY GROUP, AND ORGANOSILICON COMPOUND HAVING ACRYLOXY GROUP
Document Type and Number:
WIPO Patent Application WO/2024/090337
Kind Code:
A1
Abstract:
Provided is a production method comprising subjecting a siloxyalkylhalosilane compound represented by general formula (1) (R1 represents a monovalent hydrocarbon group, R2 represents a divalent hydrocarbon group, R3 represents a hydrogen atom or a monovalent hydrocarbon group, R4 represents a monovalent hydrocarbon group, X represents a chlorine atom or a bromine atom, m represents 0, 1, or 2, and n represents 0, 1, 2, or 3) and a carboxylic acid halide represented by general formula (2) (R5 represents a hydrogen atom, a chlorine atom, or a monovalent hydrocarbon, and X is the same as above) to a siloxy-(meth)acryloxy exchange reaction in the presence of at least one metal compound selected from the group consisting of zinc, copper, and iron, to obtain an organosilicon compound having a (meth)acryloxy group, represented by general formula (3) (R2-R5, X, and m are the same as above). In principle, the production method does not produce a (meth)acrylic adduct or a bis-adduct, and stably provides an organosilicon compound having a (meth)acryloxy group in high yield and high purity.
