\nRésumé: Since the pioneering work of Shvo and Noyori\, imp
 ressive developments have been achieved in metal-ligand cooperative cataly
 sis. Here\, the ligands not only modulate the stereoelectronic properties 
 of the metal but also participate directly in the catalytic process (exhib
 iting the so-called non-innocent character)\, and such metal-ligand cooper
 ation enables to activate/form chemical bonds under mild conditions. Over 
 the last two decades\, spectacular progress has been achieved in metal-lig
 and cooperative catalysis using pincer complexes. In particular\, Milstein
  discovered an original aromatization/dearomatization process in pyridine-
 based pincer complexes.1 
\nRecently\, we described original indenediide P
 d(II) pincer complexes (see scheme) combining an electrophilic Pd center a
 nd an electron-rich ligand backbone.2 The non-innocent character of the in
 denediide ligand has further been applied in the catalytic intramolecular 
 addition of carboxylic acids/amides to alkynes. The reaction occurs in the
  absence of external base\, thanks to a metal-ligand cooperative mode of a
 ction.3 The lactones/lactams are obtained with high selectivity and the re
 action is unprecedentedly broad in scope\, in particular concerning large 
 cycles (> 6 membered rings). The impact of the ligand modulation and varia
 tion of the metal center on the course of the reaction will also be discus
 sed.
