Stable Geminal Dianions as Precursors for Gem-Diorganometallic and Carbene Complexes,ization of the gem-dilithio species. It is particularly noticeable that at least one high valent phosphorus moiety is needed to isolate the desired precursor in high yield and purity. For each family of complexes, the question of the nature of the metal–ligand interaction is addressed as well as their general reactivity.作者: flaunt 時間: 2025-3-22 10:20 作者: Curmudgeon 時間: 2025-3-22 12:53
Dynamics of the Lithium Amide/Alkyllithium Interactions: Mixed Dimers and Beyond,eir relevance to the enantioselective process is discussed. Since the Curtin–Hammett principle forbids to correlate the complexes to the final ee‘s of the products, we have run complementary experiments of which results led us to propose the participation of an ephemeral, but more reactive, triptych aggregate.作者: Melanocytes 時間: 2025-3-22 19:23 作者: overture 時間: 2025-3-22 23:58 作者: 雪上輕舟飛過 時間: 2025-3-23 02:14

Dynamics of the Lithium Amide/Alkyllithium Interactions: Mixed Dimers and Beyond,, one of the simplest reaction meant to create a C–C bond, using dipolar bimetallic systems. Interestingly, these very popular and useful chemical transformations, even if taught at the undergraduate level, have remained underdeveloped when it comes to their enantioselective versions.
