Name: 3,5-Dimethyl-1H-pyrazole. I found the field of Chemistry very interesting. Saw the article New arylselanylpyrazole-copper catalysts: Highly efficient catalytic system for C-Se and C-S coupling reactions published in 2019.0, Reprint Addresses Stieler, R; Schneider, PH (corresponding author), Univ Fed Rio Grande do Sul, Inst Quim, POB 15003, BR-91501970 Porto Alegre, RS, Brazil.. The CAS is 67-51-6. Through research, I have a further understanding and discovery of 3,5-Dimethyl-1H-pyrazole.
We describe herein the use of arylselanylpyrazole copper complexes as versatile catalysts for C-Se and C-S coupling reactions. The performance of these complexes for C-Se reactions was investigated in chalcogenoacetylene synthesis. The reactions were carried out under mild and aerobic conditions and afforded selanylalkynes bearing a variety of electron-withdrawing and electron-donating groups. The performance of these catalysts for C-S coupling was investigated through the reaction of aryl halides with thiols and products were obtained in moderate to excellent yields. A plausible mechanism for selenoacetylene synthesis is also suggested, and the Se-77-NMR results show that these arylselanylpyrazole ligands act as hemilabile ligands. High-resolution mass spectrometry was used to investigate the intermediates and also to corroborate the proposed catalytic cycle.
