The intramolecular addition of a benzylic cation to a vinylsilane was studied. The benzylic (methoxyethoxy)methyl ether 1 was shown to undergo an unusual cyclization to afford a substituted cycloheptene (12) upon treatment with a Lewis acid. Following cyclization, the molecule undergoes a formal 1,3-hydride shift, followed by elimination to give styrene 12.
