Unusual product distributions in the dehydrobrominations of dibromomethylcyclohexanes
Abstract
Dehydrobromination of either 1,2-dibromo-1-methylcyclohexane or 1,2-dibromo-4-methylcyclohexane, in a bis-(2-methoxyethyl) ether–sodium methoxide mixture, produces products unusually rich in the exocyclic isomer 3-methylenecyclohexene.
