In-situ formed aryl acid-triggered intramolecular dehydrative cyclization whilst supported Pd-catalyzed carbonylative synthesis of 2-aryl benzimidazoles

Supported Pd-catalyzed ring opening and chemoselective aminocarbonylative coupling of benzoxazoles with aryl iodides

“…In this context, considering our previous developments in heterogeneous catalysis and carbonylation reactions, 12,13 we have established an easily accessible recyclable Pd@PS nano-catalyzed, ligand and direct CO gas free protocol for the synthesis of N -(2-hydroxyphenyl)benzamide scaffolds. The polystyrene supported palladium (Pd@PS) nanocatalyst is prepared by our previously established reduction deposition method and the formation of Pd@PS NPs is reconfirmed through SEM, TEM, and P-XRD techniques in order to identify the exact particle size and uniformity in the distribution of nanoparticles over the solid polymer matrix (Amberlite IRA 900 Cl − resin).…”
