The reactivity of a new type of organometallicintermediate, vinylidene-π-allyl palladium species, has been demonstrated: the reaction between 4-alken-2-ynyl carbonates and stabilized carbon nucleophiles afforded functionalized 1,2,3,-butatriene compounds in moderate to high yields and excellent regioselectivities.

Diels-Alder reactions of 1,2,3,4-tetrachloro-, 1,2,3,4-tetrachloro-5,5-dimethoxy-, and hexachlorocyclopentadienes with vinyl- and allylacetylene dienophiles were studied. Kinetic parameters of these reactions were determined, and the cycloaddition processes were assigned to the "neutral" type involving symmetric arrangement of the highest occupied and lowest unoccupied molecular orbitals of the diene and dienophile. Vinylacetylene derivatives were found to be more reactive than allylacetylenes. Increase in the number of chlorine atoms in the bicycloheptene fragment of the adduct favors its acetylene-allene isomerization.
