The direct experimental observation of the ligand- assisted C–H activation has not yet been reported due to the lack of well-defined isolated palladium complexes with MPAAs that can serve as models. In this work, palladium complexes bearing chelating MPAAs (NBu4)[Pd(k2-N,O–AcN–CHR–COO)(C6F5)py] (Ac = MeC(O); R = H, Me) and [Pd(k2-N,O–MeNH– CH2–COO)(C6F5)py] have been isolated and characterized. Their evolution in a solution containing toluene leads to the C–H activation of the arene and the formation of the C6F5–C6H4Me coupling products. This process takes place only for the ligands with an acyl protecting group, showing the cooperating role of this group in a complex with a chelating MPAA, therefore experimentally validating this working model. The carboxylate group is inefficient in this C–H activation.Ministerio de Ciencia e Innovación/AEI; Grant PID2019-111406GB-I00Junta de Castilla y León-FEDER; Grant VA224P20European Union / Ministerio de Ciencia e Innovación/Junta de Castilla y León; Grant C17.I01.P01.S21, H2MetAmo.Royal Society of Chemistry2023info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://doi.org/10.1039/d3sc02076bhttps://uvadoc.uva.es/handle/10324/65047reponame:UVaDOC.
