Hidrocarburos como reactivos en reacciones de acoplamiento cruzado C–C catalizadas por paladio: Ventajas y retos con una mirada mecanística

Abstract

The direct functionalization of hydrocarbons catalyzed by palladium complexes allows the formation of new C–C bonds from the available raw materials, avoiding the need to prepare the reactants needed in conventional C–C cross coupling reactions. Thus, this is a more sustainable alternative. These reactions require the activation of C–H bonds which is a difficult process, and it is affected by serious selectivity issues. This article is intended to give an overview of the types of C–H functionalization reactions catalyzed by palladium complexes, as well as the main approaches in the area to achieve more active catalytic systems and more selective reactions.
