Pd-Guanidine@Boehmite: Chemoselective, Phosphine-Free and Practical Nanocatalyst in Carbon-Carbon Cross Coupling Reaction
18 Pages Posted: 6 Jun 2020
Boehmite nanoparticles were synthesized via Al(NO3)3⋅9H2O and NaOH solution and then, an complex of Pd was fabricated on its surface (Pd-Guanidine@boehmite). This nanocatalyst was used as practical and recoverable nanocatalyst for the chemoselective C-C band formation such as Mizoroki-Heck and Suzuki–Miyaura reactions without phosphine ligands or inert atmosphere. This catalyst has been characterized by some analysis such as EDS, WDX, SEM, TGA, AAS, and BET. Also, obtained products from C-C coupling reactions were identified by NMR spectroscopy and melting points. This catalyst was recycled in described reactions without palladium leaching under reaction conditions.
