Paragraph 0035-0039, (2020/08/29)
The invention discloses a synthetic method for preparing aryl or alkenyl silane by taking alkenyl chlorosilane as a raw material and carrying out coupling reaction on the alkenyl chlorosilane, an aryland an alkenyl electrophilic reagent. The invention relates to an organosilane synthesis method based on alkenyl chlorosilane coupling reaction. According to the method, alkenyl chlorosilane is usedas a raw material, Mn or Zn is used as a reducing agent under the catalysis of nickel, and the alkenyl chlorosilane and an aryl or alkenyl electrophilic reagent are subjected to a coupling reaction togenerate an R-Si (vinyl) R1R2 type aryl with a structure as shown in a formula II or alkenyl organosilicon compound with a structure as shown in a formula III. According to the invention, the aryl and alkenyl electrophilic reagents are used as substrates to prepare the organosilicon compound with a structure of R-Si (vinyl) R1R2 type, and the method has the advantages of mild reaction conditions,simple and easily available raw materials, wide substrate applicability, good compatibility of reaction functional groups and the like.

The cross-electrophile coupling has become a powerful tool for C?C bond formation, but its potential for forging the C?Si bond remains unexplored. Here we report a cross-electrophile Csp2-Si coupling reaction of vinyl/aryl electrophiles with vinyl chlorosilanes. This new protocol offers an approach for facile and precise synthesis of organosilanes with high molecular diversity and complexity from readily available materials. The reaction proceeds under mild and non-basic conditions, demonstrating a high step economy, broad substrate scope, wide functionality tolerance, and easy scalability. The synthetic utility of the method is shown by its efficient accessing of silicon bioisosteres, the design of new BCB-monomers, and studies on the Hiyama cross-coupling of vinylsilane products.
