WebChanging the solvent from cyclohexane (CyH) to CHCl 3 significantly improved conversion and even allowed us to reduce the temperature to boost selectivity (Table 1, entries 2, 3, and 8). Encouraged by these results, we decided to fine-tune the acidity and active site topography of the catalyst by judicially varying 3,3′-positions of BINOLs and inner core … Web5 de jul. de 2024 · Le cyclohexène est un alcène ou une oléfine cyclique dont la formule moléculaire est C6H10. Il se compose d'un liquide incolore, insoluble dans l'eau et miscible avec de nombreux solvants organiques. Il se caractérise par être inflammable et, dans la nature, il se trouve généralement dans le goudron de houille.
