2-Bromo-3-methyl-2-butene is a vinylic bromide compound. Palladium/di-1-adamantyl-n-butylphosphine-catalyzed reductive carbonylation of 2-bromo-3-methyl-2-butene has been reported. Cross-coupling reaction of 2-bromo-3-methyl-2-butene with potassium 6-(benzoyloxy)hexyltrifluoroborate and 3-(benzoyloxy)propyltrifluoroborate has been investigated.
