Trifluoromethyl (CF3) groups are versatile structural motifs especially in the field of agrochemicals and pharmaceuticals. However, current trifluoromethylation reactions generally associated with stoichiometric amounts transition metals/metal oxidants, homogeneous catalysts, high temperatures, expensive trifluoromethylating agents. In this work, photocatalyst Ru(bipy)32+ is entrapped pores a faujasite support (EMC-1) via "ship-in-a-bottle" strategy. The formation coordination compound was confirmed by Fourier transform infrared (FTIR), UV-Vis spectroscopy, X-ray absorption spectroscopy (XAS). Due to its stability toward acidified environments, single-site heterogeneous catalyst suitable for synthetically interesting (hetero)arenes under visible-light irradiation at room temperature. Furthermore, could efficiently be reused least three times minimal leaching/deactivation.
