A 1,2-silicon shift in cyclopropylidenes leading to 1-trialkylsilylcyclopropenes
摘要:
1,1-Dibromo-2-trialkylsilylcyclopropanes, readily prepared by dibromocyclopropanation of vinyltrialkyl-silanes, react with methyllithium at -90 to 20-degrees-C to give high yields of trialkylsilylcyclopropenes in which the silicon has apparently migrated to C-1.
