Rearrangement of o-(chloromethyldimethylsilyl)phenylmethoxide: evidence for an apical position of the migrating group in a trigonal bipyramid intermediate
Abstract
Chloromethylsilane 5a undergoes a rearrangement reaction to give oxasilacyclopentane 9 rather than oxasilacyclohexane 10, indicating that the methyl group migrates in preference to the aryl group.
