The development of efficient ligands is well recognized to be crucial for the widespread applications of coordination polymers. Herein, we reported the preparation, structural characterisation and catalytic applications of zirconium (Ⅳ) coordination polymer (Zr‐IDA), which was derived from 1‐(carboxymethyl)‐1H‐indazole‐5‐carboxylic acid. The Zr‐IDA catalyst was composed of porous and highly crystallized

Copper-catalyzed oxidative esterification of aldehydes with dialkyl peroxides has been developed. This protocol affords a novel approach for the synthesis of carboxylic esters of tertiary alcohols under mild conditions. Depending on the catalyst system, a variety of tertiary esters were produced in good to excellent yields.
