We demonstrate the one-pot synthesis of highly porous crystalline metal−organic frameworks, [Zn<sub>4</sub>O(piperazine dicarbamate)<sub>3</sub>], an analogue of [Zn<sub>4</sub>O(1,4-benzenedicarboxylate)<sub>3</sub>] (MOF-5), directly from atmospheric pressure CO<sub>2</sub> gas and piperazine derivatives at 25 °C. The structures showed high CO<sub>2</sub> contents over 30 wt% and surface areas of 1270−2366 m<sup>2</sup> g<sup>−1</sup>. We also show that the synthesis is feasible even by the use of 400 ppm of CO<sub>2</sub>.

General Synthesis

We reported a novel simplified synthetic procedure for the preparation of monosubstituted piperazine derivatives which can now be easily prepared in a one-pot-one-step way from a protonated piperazine with no need of introduction of a protecting group. Reactions, proceeding either at room or higher temperatures in common solvents, involve heterogeneous catalysis by metal ions supported on commercial polymeric resins. A general synthetic scheme was successfully applied to afford a wide range of monosubstituted piperazines. Furthermore, we picked up a set of piperazine derivatives and studied the possibilities of microwave acceleration of given synthetic reactions to make them even more efficient. Our research proceeded from a simple batch technique to the construction of a flow microwave reactor prototype and resulted in promising findings which are summarized and discussed in the article.
