<p>PROBLEM TO BE SOLVED: To simply and efficiently produce alkynylsilanes having wide uses as an organic synthetic reactant, etc., such as a protecting group or an alkynylating agent in high yield by reacting a specific halosilane with an alkynylcopper. SOLUTION: A halosilane represented by formula I [R<1> is H, an alkyl, an aryl, an alkenyl or an alkynyl having no acetylenic hydrogen; X is a halogen; (n) is an integer of 0-3] (e.g. chlorotrimethylsilane) is reacted with an alkynylcopper represented by formula II (R<2> is an alkyl, a cycloalkyl, an aryl, an alkenyl, an alkynyl having no acetylenic hydrogen, an alkoxy, silyl or an acyl) (e.g. phenylethynylcopper) to thereby simply and efficiently afford the objective alkynylsilane represented by formula III and having wide uses as an organic synthetic reactant, etc., such as a protecting group or an alkynylating agent [e.g. trimethyl(phenylethynyl)silane].</p> |
