,N-Heterocyclic Carbenes in Catalysis—An Introduction,N-Heterocyclic carbene (NHC) has become a major ligand class and has proven to be more than just a “phosphine mimic”. Some important features like electronic and steric properties are discussed and typical examples of NHC are given herein.作者: Frisky 時(shí)間: 2025-3-22 11:54 作者: PLUMP 時(shí)間: 2025-3-22 12:59 作者: Melatonin 時(shí)間: 2025-3-22 20:12

Chiral N-Heterocyclic Carbenes as Stereodirecting Ligands in Asymmetric Catalysis,mber of highly selective chiral catalysts based on chiral NHCs having been reported very recently, several general trends in the design of new NHC-containing molecular catalysts for stereo-selective transformations in organic synthesis have emerged. This development is the focus of this review.作者: 贊美者 時(shí)間: 2025-3-23 15:25 作者: overshadow 時(shí)間: 2025-3-23 20:40

N-Heterocyclic Carbenes as Ligands for High-Oxidation-State Metal Complexes and Oxidation Catalysisis. Their strong sigma-donating ability stabilizes metals in high oxidation states, and their high M—L bond dissociation energies reduce their tendency to dissociate and undergo oxidative decomposition of the free carbene. In this chapter, we summarize these unique properties and survey the use of N作者: AVANT 時(shí)間: 2025-3-25 18:39 作者: 胡言亂語 時(shí)間: 2025-3-25 20:05 作者: Munificent 時(shí)間: 2025-3-26 02:05
