The Immobilization of homogeneous metal catalysts onto the solid surface is an important challenge in the field of catalysis because these types of catalysts provide the homogeneous nature as well as reusability of catalysts. In this report, novel Palladium ion containing ionic liquid immobilized onto graphene oxide (Pd@GOIL) and characterized using various analytical techniques like FT-IR, XPS, TGA, SEM, TEM, BET and EXAFS analysis. This synthesized material acts as a highly efficient catalyst for the alkoxycarbonylation, aminocarbonylation and phenoxycarbonylation reactions from easily available aryl iodides. Effect of various reaction parameters like CO pressure, base, solvent, the effect of time and temperature using Pd@GOIL catalyst were examined. This catalyst also tolerates the wide variety of substrates with the effective electronic factor. Specifically, this catalyst shows excellent catalytic performance towards the esterification and amidation without the need of any ligands, co-catalysts and additives. Additionally, the catalyst shows superior recyclability up to eight recycle runs without discernible activity and selectivity deterioration.
