Rearrangement reactions in 1-methyl-2-vinylsilacyclopropane
Abstract
1-Methyl-2-vinylsilacyclopropane, formed by addition of methylsilanediyl (methylsilylene) to buta-1,3-diene, is shown by deuterium labelling to undergo rearrangements initiated by both a 1,2- and a 1,5-hydrogen shift; the former is more important, especially at lower temperature.
