Reaction of hexamethyldisiloxane with 2-ethoxy-1,3-dioxolane

The reaction of hexamethyldisiloxane with 2-ethoxy-1,3-dioxolane is described. It is shown that cleavage of the endo- and exocyclic carbon-oxygen bonds of the ortho ester occurs under mild conditions (16–20C) in the presence of acidic catalysts with the formation of 2-(trimethylsiloxy)ethyl formate, the subsequent transformation of which leads to ethyl formate, trimethylethoxysilane, and 1,2-bis(trimethylsiloxy)ethane.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 12, pp. 1607–1611, December, 1989.
