| 英文摘要 | A new class of tunable metallacrown ether rhodium catalysts based on ,-(phosphine-phosphite) polyether ligands were prepared either by a template-induced method or by a nontemplate procedure. For the asymmetric hydrogenation of -arylenamides with the addition of K+ cations, the ortho-diphenylphosphine-substituted metallacrown ether catalyst showed high enantioselectivities (up to 99%ee), which are comparable to or better than the results obtained for phosphine-phosphite ligands with two or more chiral elements. Remarkable enhancements in enantioselectivity and noticeably increased catalytic activity were achieved through the supramolecular recognition between K+ cations and the metallacrown ether catalyst. |
