Pd-catalyzed functionalization of 1,3-enynes via alkylene-π-allylpalladium intermediates

In recent years, the concept of transition metal-catalyzed functionalization of unsaturated hydrocarbons has emerged as a promising strategy for developing new and valuable reactions, and has attracted considerable attention because it is efficient and atomic economical. In this critical review, we describe recent advances that have been made in the development of transition metal-catalyzed functionalization of 1,3-enynes via alkylene-π-allylpalladium intermediates.
