A synthesis of 2-aryl-, 2-(1-alkenyl)-, and 2-alkyl-1,3-butadiene derivatives (2) by the palladium-catalyzed cross-coupling reaction of 2,3-butadienyl carbonates (1) with 9-alkyl-9-bicyclo[3.3.1]nonanes (9-alkyl-9-BBN), 1-alkenylboronic acids, or arylboronic acids is described. The reaction proceeded regioselectively with the palladium-phosphine complexes under neutral conditions.
