Abstract

Abstract Under the agency of the potent lithiating agent, n-butyllithium in TMEDA, an array of organosilanes was found to undergo 1, n-silyl rearrangements via carbanionic intermediates. Unambiguous 1, 2-, 1, 3-and 1, 4-silyl shifts were uncovered in 1-trimethylsilyl- 1, 1, 2-triphenylethane, 1, 1-bis (trimethylsilyl)-1-phenylalkanes and 1, 2-bis (trimethylsilyl)-1, 2-diphenylethane, respectively. Cross-over and competition experiments established that ...
