The molecular structures of complexes 1-4 and 6 were determined by X-ray diffraction studies. The catalytic activity of the complexes (1-9) was evaluated in alpha(alpha)-alkylation reactions of ketones with alcohol via the borrowing hydrogen strategy under mild conditions. These complexes were able to perform this catalytic transformation in a short time with low catalyst and base amounts under an air atmosphere. Also, the Pd-II-nitron complexes (6-9) were applied in the Suzuki-Miyaura C-C coupling reaction and these complexes successfully initiated this reaction in a short time (30 minutes) using the H2O/2-propanol (1.5 : 0.5) solvent system. The DFT calculations revealed that the Pd-0/II/0 pathway was more preferable for the mechanism.eninfo:eu-repo/semantics/closedAccessN-Heterocyclic CarbeneCatalyzed Alpha-AlkylationMetal-ComplexesAb-InitioKetonesAlcoholsReactivityLigandsBearingStabilityArticle4946169031691510.1039/d0dt02937h33185233Q2WOS:000597124500037Q2
