I found the field of Chemistry very interesting. Saw the article Effective and Reversible Carbon Dioxide Insertion into Cerium Pyrazolates published in 2020.0. Recommanded Product: 3,5-Dimethyl-1H-pyrazole, Reprint Addresses Anwander, R (corresponding author), Eberhard Karls Univ Tubingen, Inst Anorgan Chem, Morgenstelle 18, D-72076 Tubingen, Germany.. The CAS is 67-51-6. Through research, I have a further understanding and discovery of 3,5-Dimethyl-1H-pyrazole
The homoleptic pyrazolate complexes [Ce-4(III)(Me(2)pz)(12)] and [Ce-IV(Me(2)pz)(4)](2) quantitatively insert CO2 to give [Ce-4(III)(Me(2)pzCO(2))(12)] and [Ce-IV(Me(2)pzCO(2))(4)], respectively (Me(2)pz=3,5-dimethylpyrazolato). This process is reversible for both complexes, as observed by in situ IR and NMR spectroscopy in solution and by TGA in the solid state. By adjusting the molar ratio, one molecule of CO2 per [Ce-IV(Me(2)pz)(4)] complex could be inserted to give trimetallic [Ce-3(Me(2)pz)(9)(Me(2)pzCO(2))(3)(thf)]. Both the cerous and ceric insertion products catalyze the formation of cyclic carbonates from epoxides and CO2 under mild conditions. In the absence of epoxide, the ceric catalyst is prone to reduction by the co-catalyst tetra-n-butylammonium bromide (TBAB).
