Mechanosynthesis of [60]Fullerene-Fused Tetrahydropyridines with Magnesium Nitride as the Nitrogen Source

A three-component synthesis of [60]fullerene-fused tetrahydropyridines was developed via the reaction of [60]fullerene with chalcones in the presence of magnesium nitride as the nitrogen source under ball-milling conditions. This method utilizes easily available starting materials, eliminates the need for metal catalysts and ligands, and delivers the products under mild conditions. Furthermore, one of the synthesized products was successfully employed as an interlayer in perovskite solar cells to increase the power conversion efficiency.
