Work is focused on OHCP-PdNPs synthesis with the help of meso-modified OHCP derivatives. OHCP-PdNPs utilized for the C-C coupling reactions as an efficient nanocatalyst. This study includes the stability as well as pH studies of fine PdNps. OHCP is an electron-rich ligand that is capable of reducing as well as encapsulate the metal ions because of the availability of electron-rich hydrazide functional group and H-bonding promoter four pyrrole units. In comparison with normal hydrazine, CP-hydrazide has a higher withdrawal ability, so Pd-NPs periphery is surrounded by them and undergoes stronger web-like capping on palladium. Similarly, OHCP-PdNPs are aqueous and air-stable, besides affordable alternatives for the synthesis of stable PdNPs. Moreover, encapsulating the periphery of PdNPs using OHCP enhances its activity and selectivity. Which indicates the perfect association of metal-cage recognition? This recognition may lead to numerous promising applications towards an efficient catalytic activity.
