Reactivity of dichlorosilanes with lithium ester enolates: synthesis of 3,3-disubstituted 3-silaglutarates

3,3-Disubstituted 3-silaglutarates were synthesized by reaction of the lithium enolate of ethyl acetate with dichlorosilanes at -94 deg C.When a phenyl group is linked to the silicon atom the reaction in THF gave mainly the silaglutarate.In other cases alkylsilylketene acetals were formed in proportions similar to or greater than that of the silaglutarate.The presence of HMPA increased the ratio of C- to O-silylated products and allowed the preparation of 3,3-dialkyl 3-silaglutarates in good yield.Keywords: 3-silaglutarates; Dichlorosilanes; Lithium enolates

METHOD FOR PREPARING ARYLALKOXYSILANES BY DEHYDROGENATIVE SILYLATION

Claimed is a method involving dehydrogenative silylation of aromatic compounds under Rh-catalysis to give an arylalkoxysilane. The method includes the steps of: 1) combining, under conditions appropriate to form the arylalkoxysilane, starting materials including A) an alkoxysilane having at least one silicon bonded hydrogen atom per molecule; (I) B) an aromatic compound having a carbon-hydrogen bond; and C) a rhodium bisphospholane catalyst. Additional starting materials such as D) a hydrogen acceptor and/or E) a solvent may be added during step 1). The method may further include 2) recovering the arylalkoxysilane. In a preferred embodiment the Rhodium bisphospholane catalyst is of type (II).

Synthesis of phenyl-methyl dialkoxy silane method of the

The invention relates to a method for synthesizing phenyl methyl dialkoxyl silane with high selectivity. The structural formula of phenyl methyl dialkoxyl silane is PhMeSi(OR)2, in which R is alkyl with 1-6 carbons. The method is characterized by comprising the following steps of: performing reaction with methyl trialkoxyl silane based on non-cyclic ether compounds such as ethyl ether as a reaction liquor and a bromobenzene Grignard reagent as a raw material; and then, obtaining the target compound, i.e., phenyl methyl dialkoxyl silane with high selectivity and high yield through simple filtering and fractional purification, and meanwhile, greatly inhibiting the generation of a byproduct diphenyl methyl alkoxyl silane.
