In this review, the Pd‐catalyzed coupling reaction involving propargylic/allenylic species is discussed. In these reactions, η 1 ‐ and η 3 ‐propargylic/allenylic species have been proposed as the key intermediates for the selective formation of either allenes or alkynes. It should be noted that, in most cases, allenes are formed as the major products. Electronic, steric, and ligand effects have been observed for the control of the regioselectivity.
