Catalytic and Photoluminescence Properties of the First- and Second-Sphere Coordination of Lanthanide Complexes. [PDF]

open access: yesChemistry
The Michael donor and the Michael acceptor are activated via hydrogen bonding interactions within the second‐sphere coordination of europium complexes. Abstract The efficient binding of receptors Lk (Lk = L5‐L8) to [Eu(hfac)3] (H‐hfac = 1,1,1,5,5,5‐hexafluoropentane‐2,4‐dione) allows (i) to gather the basic unit‐containing tridentate ligands Lk and the

Dearomative Nucleophilic Addition of Lithium Enolates to Electron-Poor Indoles. [PDF]

open access: yesChemphyschem
Electrophilic electron‐depleted indoles undergo 1,4‐addition to afford the dearomatized products, with complete diastereoselectivity, after smooth hydrolysis. While 3‐nitroindoles readily furnish the corresponding nitroindolines, α‐ketoamide indoles show a more complex reactivity, undergoing either 1,2‐ or 1,4‐addition, depending on the steric ...
