Abstract: Abstract Convenient synthesis of a new family of chiral ferrocene/indole-based diphosphine ligands, (Rc,Rp)-IndoFerroPhos (L), from (Sc,Rp)-PPFA and 2-(diphenylphosphino)indole has been described. These new ligands exhibited high efficiency in the Rh-catalyzed asymmetric hydrogenation of functionalized olefins… read more here.

Abstract: We present a mechanistic proposal for the desymmetrisation of dimethoxy silanes with alkyllithiums. The stereochemical pathway is highly defined by the coordination of the metal lithium, which suppresses the reversible interconversion of the various pentavalent… read more here.

Abstract: 1,2,3-Triazol-5-ylidenes have recently attracted considerable attention as versatile ligands because of their strong electron-donating properties and structural diversities. While some efforts have been devoted to the development of chiral triazolylidene-metal complexes, there is no example… read more here.

DOI: 10.1055/a-2089-4934
Abstract: Chiral ferrocene derivatives possessing planar stereogenic unit are important as chiral catalysts or materials. The principled method to obtain 1,2-disubstituted planarly chiral ferrocenes was base-mediated ortho-metalation performed on a chiral ferrocene derivative, typically using organolithium… read more here.

Abstract: Cholesteric liquid crystals (CLC) were widely used in optical devices as one-dimensional photonic crystals. However, their reflective bands cannot be adjusted, which limits their wide application in many fields. In this paper, a series of… read more here.
