Specifically, barium titanate activates aryl diazonium salts toward
Grinding piezoelectric barium titanate (BaTiO 3), aryl diazonium salt, and furan with a ball mill allows organic synthesis of aryl furan compounds. The force-induced deformed BaTiO 3 particles can act as reductants to produce radicals for further organic reaction, and also as oxidants to quench the radical addition intermediate by single-electron transfer (SET) redox reaction.
