Abstract: The paper presents the results of a comparative analysis of the differential selectivity of the Suzuki–Miyaura reaction with aryl bromides using various heterogeneous Pd precursors ( and Pd0) obtained by chemical modification and laser electrodispersion of palladium on heterogeneous supports of two types: SiO2 modified with an ionic liquid and γ-Al2O3. The catalytic experiments were carried out under "ligand-free" conditions implying no additives of phosphines, amines, carbenes, or any other organic ligands for Pd stabilization. Changes in the differential selectivity of competing aryl bromides were observed while varying the nature and concentration of the Pd precursor, indicating a substantial contribution of true heterogeneous catalysis to the total conversion of substrates.
