A General and Selective Synthesis of Methylmonochlorosilanes from Di-, Tri-, and Tetrachlorosilanes

Direct catalytic transformation of chlorosilanes into organosilicon compounds remains challenging due to difficulty in cleaving the strong Si-Cl bond(s). We herein report the palladium-catalyzed cross-coupling reaction of chlorosilanes with organoaluminum reagents. A combination of [Pd(C3H5)Cl]2 and DavePhos ligand catalyzed the selective methylation of various dichlorosilanes 1, trichlorosilanes 5, and tetrachlorosilane 6 to give the corresponding monochlorosilanes.

METHOD FOR PRODUCING HALOSILANE

PROBLEM TO BE SOLVED: To provide a method for producing halosilane that can efficiently produce halosilane. SOLUTION: Alkoxy halomethane is used as a halogenating agent and reacted with oxysilane having a structure represented by formula (a), to efficiently produce halosilane having a structure represented by formula (b) (In the formula (b), X is a chlorine atom, a bromine atom, or an iodine atom).

Nickel-Catalyzed Selective Cross-Coupling of Chlorosilanes with Organoaluminum Reagents

Nickel-catalyzed cross-coupling reactions of chlorosilanes with organoaluminum reagents were developed. An electron-rich Ni(0)/PCy3 complex was found to be an effective catalyst for the desired transformation. The reaction of dichlorosilanes 1 proceeded to give the corresponding monosubstituted products 2. Trichlorosilanes 4 underwent selective double substitution to furnish the corresponding monochlorosilanes 2. Overall, the selective synthesis of a series of alkylmonochlorosilanes 2 from di- and trichlorosilanes was achieved using the present catalytic systems.
