Undirected C-H Bond Activation in Aluminium Hydrido Enaminonates [PDF]

open access: yesMolecules, 2023
Two new aluminium hydrido complexes were synthesized by reacting AlH3 with the enaminone ligand N-(4,4,4-trifluorobut-1-en-3-on)-6,6,6-trifluoroethylamine (HTFB-TFEA) in different molar ratios to obtain mono- and di-hydrido-aluminium enaminonates.

Rollover Cyclometalation as a Valuable Tool for Regioselective C–H Bond Activation and Functionalization [PDF]

open access: yesMolecules, 2021
Rollover cyclometalation constitutes a particular case of cyclometallation reaction. This reaction occurs when a chelated heterocyclic ligand loses its bidentate coordination mode and undergoes an internal rotation, after which a remote C–H bond is ...
