Abstract

To establish the mechanism of reaction (1), we studied the reaction of disiloxane I with a twofold excess of triethylsilane in the presence of colloidal nickel. As the products of this reaction, hexaethyldisiloxane (II) and 1, 1-dimethyl-3, 3, 3-triethyldisiloxane (III) were isolated and characterized. In addition, 1, 1, 3, 3-tetramethyl-5, 5, 5-triethyltrisiloxane (IV), 3, 3-dimethyl-1, 1, 1, 5, 5, 5-hexaethyltrisiloxane (V), 3, 3, 5, 5-tetramethyl-1, 1, 1, 7, 7, 7- ...
