The invention discloses a method for preparing diphenyldialkoxysilane, and the method comprises the following steps: adding a certain proportion of diphenyldichlorosilane and an acid binding agent A in a non-aqueous solvent, further adding a certain propo
Dehydrogenative Coupling of Hydrosilanes and Alcohols by Alkali Metal Catalysts for Facile Synthesis of Silyl Ethers

Cross-dehydrogenative coupling (CDC) of hydrosilanes with hydroxyl groups, using alkali metal hexamethyldisilazide as a single-component catalyst for the formation of Si-O bonds under mild condition, is reported. The potassium salt [KN(SiMe3)2] is highly efficient and chemoselective for a wide range of functionalized alcohols (99% conversion) under solvent-free conditions. The CDC reaction of alcohols with silanes exhibits first-order kinetics with respect to both catalyst and substrate concentrations. The most plausible mechanism for this reaction suggests that the initial step most likely involves the formation of an alkoxide followed by the formation of metal hydride as active species.
Synthetic method of allyl acrylate

Paragraph 0019, (2017/04/28)
The invention discloses a new synthetic method of allyl acrylate. According to the method, an organic silicon monomer with functional groups is used, and the allyl acrylate is prepared under the soft reaction condition. The synthetic method of the allyl acrylate includes three steps that (1) acryloxytrimethylsilane is synthesized; (2) allyloxy silane is synthesized; and (3) the acryloxytrimethylsilane and the allyloxy silane are mixed. According to the raw materials used in a reaction, chlorine elements are fully converted into inorganic salt, low-boiling-point chloride like phosphorus trichloride is not used, and it is guaranteed that the chlorine elements are not contained in a prepared product; reaction conditions are soft, and the requirement for the equipment is not high; purification is easy, boiling points of all components are large in difference, and reduced pressure distillation separation is easy; water washing is not needed, and amplification is easy; and trifluoromethanesulfonic acid serves as a catalyst, the high acidity is achieved, and double bonds cannot be damaged.
Silicon tethered ring-closing metathesis reactions for self- and cross- coupling of alkenols
Hoye, Thomas R.,Promo, Michele A.
, p. 1429 - 1432 (2007/10/03)
The title process can be used to couple allylic, homoallylic, and bishomoallylic alkenols. Cyclic silaketals with ring sizes from 7-11 members can all be formed. This constitutes a general and versatile strategy for approximately doubling the molecular complexity of readily available alkenol precursors.
Silaketals in Intramolecular 1,3-Dipolar Cycloaddition of Nitrile Oxides
Dogbéavou, Romain,Breau, Livain
, p. 1208 - 1210 (2007/10/03)
A one pot synthesis of unsymmetrical silaketals having a 1,2-disubstituted double bond and a nitro-group is described. These compounds undergo, under mild conditions, regiospecific intramolecular 1,3-dipolar cycloaddition to give a single 2-isoxazoline.
