Abstract:The surface of SBA‐15 mesoporous silica was modified by N‐hydroxyphthalimide (NHPI) moieties acting as immobilized active species for aerobic oxidation of alkylaromatic hydrocarbons. The incorporation was carried out by four original approaches: the grafting‐from and grafting‐onto techniques, using the presence of surface silanols enabling the formation of particularly stable O‐Si‐C bonds between the silica support and the organic modifier. The strategies involving the Heck coupling led to the formation of NHP… Show more
