A new magnetically recoverable nanocatalyst was prepared by functionalization of mesoporous silica (SBA-15) with a Schiff base ligand, and then immobilization of palladium nanoparticles on it using a simple procedure. This heterogeneous catalyst was fully characterized using appropriate analyses and its catalytic efficiency was investigated in Heck reaction using iodo-, bromo-and chlorobenzene derivatives and styrene, with the aim of synthesizing stilbene derivatives, a class of compounds with a variety of pharmacological properties. Some of the characteristics of this nanocatalyst include good dispersion of palladium nanoparticles on the SBA-15 support, easy separation, catalyses the production of stilbene derivatives in a short time with excellent yields even for bromo-and chlorobenzene, and preservation of its catalytic activity after eight reaction cycles.

A supermagnetic core–shell nanocatalyst functionalized with a dipeptide ligand as a recyclable catalyst for the selective oxidation of alcohols.
