Paragraph 0097-00107; 00108-00110, (2021/06/26)
A method of preparing an organosilicon compound via selective silylation of ethylene is disclosed. The method comprises reacting via silylation (A) a hydridochlorosilane compound and (B) ethylene in the presence of (C) a catalyst, thereby preparing the organosilicon compound. The silylation may be selectively conducted as a dehydrogenative coupling to prepare the organosilicon compound as a vinylchlorosilane compound, or as a hydrosilylation to prepare the organosilicon compound as an ethylchlorosilane compound. The catalyst (C) comprises a Ru(0) complex, and may be recycled for use in subsequent silylation reactions without purification. The organosilicon compound prepared according to the method is also disclosed.

Silylation of ethylene by chlorosilanes is catalysed by ruthenium complexes. Mechanistic investigations reveal the presence of a complicated network of reactions leading to new σ-silane, ethylene and silyl complexes.

The regiochemistry of the electrophilic cleavage of the SiCsp3 bond in compounds Me3SiCH2Σ (Σ = Me, Pr, Cl, COOEt) and Me3SiCHΣ2 (Σ = Cl) has been investigated using ICl, Me3SiOSO2Cl and HO3SCl as the electrophiles.When Σ = Pr or Cl a regioselective cleavage of the Si-CH3 bond was observed, producing silylated chlorosulfonates or sulfates which often were new compounds.With Σ = COOEt a regiospecific splitting of the Si-CH2COOEt bond was observed.This confirms the synthetic potential of ethyl trimethylsilylacetate.
