Reactions of Ketones with Low-Valent Lanthanides: Isolation and Reactivity of Lanthanide Ketyl and he ligand effects on the reactivity of these complexes. It has been demonstrated that the stability and reactivity of the ketyl radical and ketone dianion species strongly depend on the steric and electronic properties of the ancillary ligands, the structure of their parent ketones, as well as the n作者: EWER 時間: 2025-3-23 21:21 作者: GRACE 時間: 2025-3-24 00:39 作者: 脾氣暴躁的人 時間: 2025-3-24 02:40 作者: Affection 時間: 2025-3-24 10:02

Principles in Organolanthanide Chemistry,lar emphasis is placed on synthetic aspects, i.e. optimization of established procedures and alternative methods with better access to catalytically relevant species. Accordingly, tailor-made ancillary ligands are reported in detail and the reactivity pattern of lanthanide compounds is examined with representative examples.作者: Pelvic-Floor 時間: 2025-3-25 11:14 作者: 滋養(yǎng) 時間: 2025-3-25 12:36 作者: 擴(kuò)張 時間: 2025-3-25 18:00
Lanthanide Triflate-Catalyzed Carbon-Carbon Bond-Forming Reactions in Organic Synthesis,. A catalytic amount of Ln(OTf). is enough to complete reactions in most cases. In addition, Ln(OTf). can be recovered after reactions are completed and can be reused. Several chiral lanthanide catalysts for asymmetric Diels-Alder, aza Diels-Alder, and 1,3-dipolar cycloaddition reactions are also described.作者: peritonitis 時間: 2025-3-25 22:23 作者: Override 時間: 2025-3-26 02:54 作者: Watemelon 時間: 2025-3-26 06:47

Thanks to the above tuning of the diiodosamarium reactivity, rich and diversified organic transformations have been performed, some examples of which are presented.作者: 雜役 時間: 2025-3-26 10:09 作者: Supplement 時間: 2025-3-26 15:21 作者: 變色龍 時間: 2025-3-26 17:44 作者: nitric-oxide 時間: 2025-3-27 00:52
