A mixed-linker nanoporous coordination polymer Zn2(HIP)2(bipy)(H2O)2 x H2O (ZnHipBipy) constructed from polyfunctional linker 5-hydroxy isophthalic acid (HIP) and exo-bidentate ligand 4,4'-bipyridyl (bipy) was employed as heterogeneous catalyst for allyl glycidyl carbonate (AGC) synthesis from CO2 and allyl glycidyl ether (AGE) under solventless conditions. Besides being the organic linker, 5-hydroxy isophthalic acid enriches the functionality of the material through accessible hydroxyl group capable of contributing extensive hydrogen bonding interactions. The cycloaddition of CO2 and epoxide was catalyzed through a synergistic pathway offered by inherent hydroxyl group together with the catalytically active metal centre. Method of synthesis and texture of the catalyst were key factors in determining the conversion and selectivity. The effects of reaction parameters like catalyst amount, temperature, CO2 pressure and reaction time on the yield of AGC were also studied.
