We developed a palladium-catalyzed C-H transformation that enabled the synthesis of ketones from aldehydes and (hetero)aryl halides. The use of picolinamide ligands was key to achieving the transformation. Heteroaryl ketones, as well as diaryl ketones, were synthesized in good to excellent yields, even in gram-scale, using this reaction. Results of density functional theory (DFT) calculations support the C-H bond activation pathway.
Fabrication of covalently functionalized mesoporous silica core-shell magnetite nanoparticles with palladium(II) acetylacetonate: Application as a magnetically separable nanocatalyst for Suzuki cross-coupling reaction of acyl halides with boronic acids

We report the preparation of supported palladium(II) acetylacetonate, Pd(acac)2, coordinated by pendant acac groups, by reacting palladium acetate with acac-functionalized doubly silica-coated magnetic nanoparticles. The solid support consists of an amorphous silica-coated (as magnetite protecting layer) magnetite core and a mesoporous silica shell. The magnetically separable palladium nanocatalyst is active for Suzuki cross-coupling reaction of acyl halides with boronic acids. The catalyst is simply isolated from the reaction mixture that allows fast and efficient isolation of product and catalyst compared to traditional methods that generally make use of time- and solvent-consuming procedures.
