An alkaline-resistant Ag(i)-anchored pyrazolate-based metal–organic framework for chemical fixation of CO2

Abstract

An alkaline-resistant Ag(I)-anchored metal–organic framework has been achieved via postsynthetic modification of pyrazolate-based linkers. For the first time, the resultant MOF was completely heterogeneous and recyclable over at least ten cycles in cyclic carboxylation of propargyl amines and CO₂ into oxazolidinones and tetramic acids under atmospheric pressure of CO₂.
