CH bond catalytic activation/functionalization has been matter of great interest, since these transformations could establish new grounds from the synthetic perspective, and could serve to propose alternative and greener methods for the production of organic molecules. In this sense, the development of efficient catalytic systems for CH bond activation becomes of great importance, and understanding the principles that govern such transformations, either stoichiometric or catalytic, is essential. To study such processes from the mechanistic or catalytic point of view requires of the design of ligands and catalysts able of performing CH bond activation. (P,N)-chelates have arisen as alternative ligands to develop new catalytic systems, due to their combination of different donor atoms, and the ability to tune their steric and electronic characteristics and to create potential vacant sites at the metal center due to hemilability.

This mini review summarizes the advances from 2005 to 2015 in the field of CH bond activation at transition metal centers from groups 8–10 bearing (P,N)-chelating ligands. Even when the examples of inter- or intramolecular CH bond activation using transition metal complexes with the (P,N) ligands described herein do not engage yet in catalytic applications, their understanding becomes of great importance and sets the basis for future developments in this field.

C H键催化活化/官能化一直是引起人们极大兴趣的问题，因为这些转化可以从合成的角度建立新的基础，并且可以为提出生产有机分子的替代性和绿色方法提供建议。从这个意义上讲，开发有效的C H键活化催化体系至关重要，理解控制这种化学计量或催化转化的原理至关重要。从机理或催化的观点来研究这样的过程需要设计能够进行C的配体和催化剂H键活化。（P，N）-螯合物已成为替代配体，以开发新的催化体系，这是由于它们具有不同的供体原子的组合以及调节其空间和电子特性的能力以及由于半合性而在金属中心形成潜在的空位的能力。

这篇简短的综述总结了2005年至2015年在过渡金属中心的C H键活化领域（来自8-10组含（P，N）-螯合配体）的研究进展。即使当使用本文所述的具有（P，N）配体的过渡金属配合物进行分子间或分子内C H键活化的实例尚未参与催化应用时，它们的理解也变得非常重要，并为该领域的未来发展奠定了基础场地。
