The 3 wt% CuI/BNNS catalyst exhibited high efficiency for C–H difluoromethylation reactions and enabled greener synthesis at high yields using cyrene as a solvent. Furthermore, the catalyst could be easily recovered and recycled for at least five cycles.

CuO distribution in the aluminosilicate framework and acidic sites play a multifunctional role in the reaction. 13H-Dibenzo[1,4]diazonine has been synthesized by using a 6 wt% CuO/Al-KIT-6 catalyst using ethanol as solvent.
