Abstract
N-heterocyclic carbene (NHC) ligands have become ubiquitous ligands in the preparation of metal complexes with new catalytic applications. Mainly due to their applications in C-C bond formation reactions, a plethora of novel palladium-NHC complexes has been described, and a large number of review articles describing their chemistry have been published. In an attempt to provide a new vision of the topic, this article will focus the attention on the development of new palladium complexes with NHC ligands, paying special attention to their applications in catalytic processes other than the classical C-C coupling reactions. This article is divided in the following sections: i) design of reusable Pd-NHC complexes, ii) latest advances in the use of Pd-NHC complexes in homogenous catalysis and, iii) other applications of Pd-NHC complexes.
Keywords: N-heterocyclic carbenes, palladium, catalysis, homogeneous, reciclability, asymmetric, biomedical, N-heterocyclic carbene ligands (NHC), stereoelectronic properties, organocatalysis, chiral-NHC systems, resins, enantiomeric excess, prochiral alkenes, heterobimetallic complexes

Catalytic C-H bond activation as a tool for functionalization of heterocycles
The major topic is the functionalization of heterocycles through catalyzed C-H bond activation. The strategies based on C-H activation not only provide straightforward formation of C-C or C-X bonds but, more importantly, allow for the avoidance of pre-functionalization of one or two of the cross-coupling partners. The beneficial impact of ...read more
