Title : Highly efficient functionalized calix 4 pyrrole wrapped scrupulous nanopalladium catalyst
Abstract:
Calix(4)pyrrole-palladium nanoparticles synthesis with the help of meso-modified hydroxy calix(4)pyrrole (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. This recognition may lead to numerous promising applications towards an efficient catalytic activity.
