2-Trimethylsilylethyl-1,3-butadiene, readily prepared by the cross-coupling reaction of the Grignard reagent of 3-bromo-3-butenyltrimethylsilane with vinyl bromide catalyzed by a nickel-phosphine complex, works as a synthetic equivalent to 3-methylene-1,4-pentadiene (parent [3]dendralene) by the consecutive Diels-Alder reactions.
