Palladium Catalysis: Dependence of the Efficiency of C-C Bond Formation on Carboxylate Ligand and Alkali Metal Carboxylate or Carboxylic Acid Additive. Part A: the C(sp2)-C(sp2), C(sp2)-C(sp3) and C(sp3)-C(sp3) Bonds

A variety of Pd-catalyzed reactions are carried out with palladium carboxylates in the presence of carboxylic acids and/or alkali metal carboxylates. This review is Part A of three reviews highlighting the dependence of the efficiency of the formation of the different C-C bonds on the nature of the carboxylate unit. Part A concerns inter- and intramolecular reactions leading to the formation of a C(sp(2))-C(sp(2)), C(sp(2))-C(sp(3)) or C(sp(3))-C(sp(3)) bond. The variety of procedures and additives is presented as well as the reaction mechanisms with, as far as possible, personal comments.
