Palladium Catalysis: Dependence of the Efficiency of C−C Bond Formation on Carboxylate Ligand and Alkali Metal Carboxylate or Carboxylic Acid Additive. Part C: The Domino Diarylation and Annelation Reactions

Abstract The efficiency of the formation of C−C bonds under palladium catalysis often depends on the nature of the carboxylate ligand and carboxylic acids or alkali metal carboxylates additives. This review which is Part C of a trilogy devoted to the topic, highlights the influence of the carboxylate units on domino diarylation and annelation reactions. The plausible reaction mechanisms are presented with, as far as possible, personal comments.
