With palladiumcatalysis, allyl bromides or chlorides react with α-diazocarbonyl compounds or N-mesylhydrazones to afford 1,3-diene derivatives. The reaction represents a novel and efficient method for the synthesis of 1,3-butadiene derivatives. Mechanistically, the reaction is proposed to follow a pathway involving the formation of a π-allylic palladium carbene complex and subsequent migratory insertion

A quick-setting adhesive composition comprises a 2-cyanoacrylate and at least one 1,1-disubstituted diene, the amount of said diene being greater than 50% of the total weight of the two components. This composition can be used in place of conventional 2-cyanoacrylate adhesives but has improved impact resistance, peel resistance, heat resistance and water resistance.
