Mechanisms of the arylation of hydrochlorosilanes under pressure
- 23 Downloads
Mechanisms of the silylation of aromatic hydrocarbons by hydrochlorosilanes under pressure have been proposed and substantiated on the basis of the experimental material. In the absence of catalysts, the process occurs according to the mechanism of a reaction of thermal condensation; in the presence of catalysts it proceeds by electrophilic substitution of hydrogen in the aromatic ring, beginning with the dissociation of chlorosilane at the≡Si-Cl bond. The Si-H bonds serve as an acceptor of hydrogen chloride.
