Palladium-catalyzed cross-couplings of 1,3-butadien-2-yl species with organoindiums generated from allenylmethyl bromide and indium.
An organoindium generated from the reaction of indium with allenylmethyl bromide is an efficient nucleophile in Pd-catalyzed cross-couplings, producing 1,3-butadienes; cross-couplings followed by [4 + 2] cycloadditions gave six-membered carbocycles in a one-pot process.
