Iv AgN03-C&N spectrum of this material was found to be identical with that of an authentic specimen of X prepared by the reaction of diphenyl-0-tolylsilane (IV) with an aqueous silver nitrate-pyridine mixture. l 1 Compound I is readily cleaved by phenyllithium to give, subsequent to acid hydrolysis, o-tolyltriphenylsilane (XI). 12 None of the ring-opened product XI could be isolated from I and phenylmagnesium bromide at room temperature. ...
