An alkaline-resistant Ag(i)-anchored pyrazolate-based metal-organic framework for chemical fixation of CO 2 .

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.
