Palladium assisted formation of carbon-carbon bonds was discussed. Insertion reactions of isocyanides into the Pd-C bond of orthopalladated primary amines and synthesis of 2-R-aminoisoindolinium salts were performed. Results showed that formation of this complex requires coordination of a second molecule of isocyanide per palladium through a bridge splitting process.

A study of the reactivity of the [Pd(C6H4X-2)Br(bpy)] (bpy = 2,2′-bipyridine; X = C(O)Me, CN, CHO, CH=CH2) complexes was presented. The 2-R-arylpalladium(II) complexes reacted with XyNC (Xy = 2,6-dimethylphenyl) to give different mono- and triinserted complexes depending upon the nature of X, the other ligands and the reaction conditions. The crystal structures of the prepared complexes were also reported.

Improved syntheses for the dimeric compounds [Pd2(μ-X)2(PBut3)2] (X = Br, I) have been developed and the X-ray crystal structure for the dimer with X = 1 is reported. The reactions of these dimers with CNR (R = 2,6-dimethylphenyl), H2 and a series of terminal and substituted alkynes are also reported. The dimer with X = Br is an initiator for the catalytic polymerisation of phenylacetylene. The product of the dimers with disubstituted alkynes results in the synthesis of trimeric species with formula [Pd3(μ-X){ν2-C4(CO2R) 4}2][PBut3)Me]2 (X = Br, I; R = Me, Et). The X-ray crystal structure of one of these compounds (when R = Et and X = I) is presented, demonstrating that the palladium dimers assist the C-C coupling of the alkynes.
