Demonstrating their potential: Bidentate alkoxy NHC ligands have been used in the copper‐catalyzed asymmetricallylic alkylation of allylphosphates with Grignard reagents (see scheme). The method provides access to tertiary and quaternary chiral centers with high regio‐ and enantioselectivity. The system is also applied to the synthesis of chiral E,E‐dienes, a key structural motif prevalent in natural
Structural features, chemical stabilities and catalytic profiles in olefin metathesis of a new library of low-cost cycloalkyl-based U2-NHC Ru complexes were disclosed.
