various organopalladium compounds, derived from cyclopalladated complexes in which two alkynes have been inserted into their Pd–C bonds, affords organic products containing six-membered rings. The latter are obtained either by de-alkylation of an ester group or by annulation of an aryl ring, the ester and the aryl units being substituents on the alkynes used in the synthesis of the starting materials
