Surface of mesoporous silica gel was functionalized by the reaction of catalytic N-arylation. 3-Aminopropyl-functionalized silica gel was used as a starting material. The reaction was carried out in the presence of copper acetate as a catalyst. Optimal conditions of the synthesis were determined for the reaction of terminal amino groups with phenylboronic acid. Then Br, Cl, CH3, OCH3, SCH3, CH=CH2, and CHO groups were introduced to the surface with the use of para- and meta-substituted phenylboronic acids. In addition to aromatic compounds, heterocyclic and vinylboronic acids were also used in this reaction. The presence of the functional groups was confirmed by elemental analysis and characteristic reactions. Obtained functionalized materials were studied by BET adsorption of nitrogen, DSC and TGA methods.
