I found the field of Chemistry very interesting. Saw the article A structural study of new tetrakis(1H-pyrazol-1-yl)methanes published in 2019.0. SDS of cas: 67-51-6<\/a>, Reprint Addresses Alkorta, I (corresponding author), CSIC, Inst Quim Med, Juan Cierva 3, E-28006 Madrid, Spain.. The CAS is 67-51-6. Through research, I have a further understanding and discovery of 3,5-Dimethyl-1H-pyrazole<\/p>\n

Tetrakis(1H-pyrazol-l-yl)methanes are very rare compounds of which only two are known: the unsubstituted 1 obtained classically by Wicket in 1937 from carbon tetrachloride and prepared again several times and the 3,5-dimethyl substituted 2 obtained serendipitously by Pombeiro in 2009. We have now extended this group to include four new derivatives 8, 9,11 and 12 bearing methyl groups. The X-ray crystal structure of the four compounds has been determined. They have been studied by NMR both in solution (H-1, C-13, N-15) and in the solid state (C-13 and N-15). DFT calculations of the six compounds (geometries, energies and absolute shieldings) have been used to discuss the experimental observations. (C) 2019 Elsevier Ltd. All rights reserved.<\/p>\n
