Opening claim text (preview).
1 . A method for producing a halogenated hydrocarbon magnesium compound, the method comprising contacting a halogenated hydrocarbon compound with magnesium having a specific surface area of 1×10 −5 to 2×10 −4 m 2 /g. 2 . The method for producing a halogenated hydrocarbon magnesium compound according to claim 1 , wherein the halogenated hydrocarbon compound is at least one selected from a mono-halogenated alkyl compound and a di-halogenated alkyl compound represented by the following formula (1): [Chem. 1] X—R—X (1) wherein R represents a linear or branched alkyl group having 1 to 8 carbon atoms and X represents a halogen atom. 3 . The method for producing a halogenated hydrocarbon magnesium compound according to claim 1 , wherein the halogenated hydrocarbon compound is a hydrocarbon bromide compound. 4 . The method for producing a halogenated hydrocarbon magnesium compound according to claim 1 , wherein the halogenated hydrocarbon compound is contacted with the magnesium at a temperature between −78° C. and 100° C. 5 . The method for producing a halogenated hydrocarbon magnesium compound according to claim 1 , wherein a solution containing the halogenated hydrocarbon compound is contacted with the magnesium. 6 . The method for producing a halogenated hydrocarbon magnesium compound according to claim 5 , wherein the solution containing the halogenated hydrocarbon compound is passed through a packed tower filled with the magnesium. 7 . The method for producing a halogenated hydrocarbon magnesium compound according to claim 6 , wherein the solution containing the halogenated hydrocarbon compound is repeatedly passed through the packed tower filled with the magnesium. 8 . The method for producing a halogenated hydrocarbon magnesium compound according to claim 6 , wherein a plurality of packed towers each filled with the magnesium exist and the solution containing the halogenated hydrocarbon compound is passed through the plurality of packed towers. 9 . The method for producing a halogenated hydrocarbon magnesium compound according to claim 6 , wherein the solution containing the halogenated hydrocarbon compound has a temperature between −78° C. and 100° C. 10 . A method for producing a tertiary alcohol compound, comprising: producing a halogenated hydrocarbon magnesium compound by the method according to claim 1 , and contacting the halogenated hydrocarbon magnesium compound with a ketone compound. 11 . A method for producing a tertiary alcohol compound, comprising contacting a halogenated hydrocarbon compound, a ketone compound, and magnesium having a specific surface area of 1×10 −5 to 2×10 −4 m 2 /g. 12 . A method for producing an organosilicon compound, comprising: producing a halogenated hydrocarbon magnesium compound by the production method according to claim 1 , and contacting the halogenated hydrocarbon magnesium compound with a silicon compound selected from a chlorosilane compound and an alkoxysilane compound. 13 . A method for producing an organosilicon compound, comprising contacting a halogenated alkyl compound, a silicon compound selected from a chlorosilane compound and an alkoxysilane compound, and magnesium having a specific surface area of 1×10 −5 to 2×10 −4 m 2 /g.
