Abstract
Bromination of methylene groups exocyclic to cyclohexyl systems can afford,
besides the expected trans-dibromo products,
considerable quantities of a tribromide. For example, simple bromination of
4-t-butyl-1-methylidene-cyclohexane affords c.
20% yield of (r-1, t-2,
c-4)-1,2-dibromo-1-bromomethyl-4-t-butylcyclohexane.
