  Further insight into the mechanism of the palladium induced carbocyclisation of aryl rings.

  摘要：

  The depalladation of several cyclopalladated compounds, containing two inserted diphenylacetylenes in the Pd-C bond has been achieved by treatment with either a neutral coordinating ligand such as pyridine, triphenylphosphine or maleic anhydride. This has afforded carbocyclic compounds where one or two of the aryl groups of the butadienyl chain have been annulated as a result of C-C bond formation. These demetallation reactions could be performed under rather mild conditions which enabled the characterisation of an intermediate which in turn provided valuable information about the mechanism of the palladium mediated carbocyclisation reaction.

  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
