Abstract Vinyl derivatives of disilane were found to undergo nucleophilic cleavage of the silicon silicon bond very easily in the presence of chlorides of certain noble metals. The ease of ethanolysis of the silicon silicon bond and the course of the subsequent reactions of the cleavage fragments were dependent upon the nature of metals of catalysts. The ethanolysis of vinylpentamethyldisilane (I) in the presence of platinum salts mainly gave ...
