The invention discloses a chiral dihydrosilane compound shown as a formula IV, wherein the formula IV represents a chiral carbon atom. And discloses a method for synthesizing the chiral dihydrosilane compound: using olefin shown in formula I and silane shown in formula II as raw materials, and obtaining chiral CoX 2 And (3) reacting the-OIP complex serving as a catalyst in the presence of a reducing agent to obtain the chiral dihydrosilane compound shown in the formula IV. The synthetic method is suitable for various olefins with different types, and has the advantages of mild reaction conditions, simple and convenient operation and high atom economy. The reaction does not need to add any other toxic transition metal salts, the reaction yield is better, generally 53-97 percent, the enantioselectivity is higher, generally 81-E>99 percent. The chiral dihydrosilane compound shown in formula IV can be used for synthesizing chiral alcohol compounds, chiral silanol compounds, chiral polysubstituted silane compounds and the like. |
