Activemethylenecompounds, such as acetylacetone and ethyl acetoacetate, reacted with 1,3-butadiene in the presence of palladium-diphosphine complex catalysts to yield two 1 : 1 adducts, 1 and 2. Primary and secondary amines also afforded two 1 : 1 adducts, 10 and 11. Isoprene, 1,3-pentadiene, and 2,4-hexadiene also reacted with the activemethylenecompounds and the amines in a manner similar to
