Disilane and preparation method thereof

The invention discloses disilane and a preparation method thereof. The preparation method of disilane includes: subjecting a uniformly mixed reaction system containing tertiary hydrosilane and a catalyst to dehydrogenation reaction at a temperature ranging from -10DEG C to 120DEG C to obtain disilane, wherein the catalyst comprises a silver salt. The invention also discloses the disilane preparedby the method. The method for preparation of the disilane by catalyzing tertiary silane dehydrogenation with the silver salt adopts the silver salt to activate the Si-H bond in the silane so as to realize construction of disilane. Therefore, the invention provides an efficient and simple method for preparation of the compound, and the application prospect is wide.

Method for continuously preparing disilane compounds by micro-reaction device

The invention discloses a method for continuously preparing disilane compounds by a micro-reaction device. The method comprises the following steps: (1) a solution A is prepared from organosilane by dissolving in a first organic solvent, or is organosilane; (2) a solution B is prepared from an oxidant by dissolving in a second organic solvent, or is an oxidant; (3) the solution A and the solutionB are pumped into a micro-mixer of the micro-reaction device simultaneously for mixing, a product then flows into a microreactor of the micro-reaction device for reaction, and the disilane compounds are prepared, wherein the microreactor is filled with a catalyst. Raw materials required in the method are easily available and have better stability, metal copper compounds are used as a catalyst forcoupling reaction on trisubstituted silanes, and the coupling effect on trisubstituted silanes is better than that of alkali metal catalysts and transition metal catalysts; a micro-channel reactor issuitable for an exothermic coupling reaction due to good mixing and heat transfer performance.
