A simple cooperative catalytic system was successfully developed for the solvent-free N-formylation of amines such as morpholine, 2,3-dihydro-1H-indole, 2,6-dimethylpiperazine, etc. with CO2 and hydrosilanes under ambient conditions and composed of a Zn(salen) catalyst and quaternary ammonium salt. These com. available binary components activated the Si-H bonds effectively, owing to the intermol. synergistic effect between Lewis base and transition metal center (LB-TM), and subsequently facilitated the insertion of CO2 to form the active silyl formats, thereby leading to excellent catalytic performance at a low catalyst loading. Furthermore, the bifunctional Zn(salen) complexes, with two imidazolium-based ionic-liquid (IL) units at the 3,3′-position of salen ligand, acted as intramolecularly cooperative catalysts, and the solvent-regulated separation resulted in facile catalyst recycling and reuse. In the experiment, the researchers used many compounds, for example, 1-Octyl-1H-imidazole (cas: 21252-69-7Quality Control of 1-Octyl-1H-imidazole).
1-Octyl-1H-imidazole (cas: 21252-69-7) belongs to imidazole derivatives. 1H-imidazole is an imidazole tautomer which has the migrating hydrogen at position 1. It is a conjugate base of an imidazolium cation. It is a conjugate acid of an imidazolide. It is a tautomer of a 4H-imidazole. Imidazole also acts as a microtubule destabilizing agents and inhibits topoisomerase and Cytochrome P450 Family 26 Subfamily A Member 1 (CYP26A1) enzymes.Quality Control of 1-Octyl-1H-imidazole
