METHOD FOR PRODUCING ORGANOSILICON COMPOUND USING HALOSILANE AS RAW MATERIAL

PROBLEM TO BE SOLVED: To provide a novel method for producing an organosilicon compound. SOLUTION: The method for producing an organosilicon compound includes a reaction step (I) of reacting a halosilane represented by formula (a) with a compound containing a hydrocarbon group represented by formula (b) in the presence of an organic base to generate an organosilicon compound represented by formula (c). (In the formula (I), n is an integer of 0-3; each R1 independently represents a hydrogen atom or a C1-20 hydrocarbon group which may contain a heteroatom; X represents a bromo group (-Br) or a chloro group (-Cl); and R2 represents a compound containing a hydrocarbon group.)
