Lithium-mediated Ferration of Fluoroarenes
Autor: Lewis C. H. Maddock, Alan Kennedy, Eva Hevia
Publikováno v: CHIMIA, Vol 74, Iss 11, Pp 866-870 (2020)
While fluoroaryl fragments are ubiquitous in many pharmaceuticals, the deprotonation of fluoroarenes using organolithium bases constitutes an important challenge in polar organometallic chemistry. This has been widely attributed to the low stability

Utilising Sodium-Mediated Ferration for Regioselective Functionalisation of Fluoroarenes via C−H and C−F Bond Activations
Autor: Alan R. Kennedy, Michael R. Probert, Tracy Nixon, Lewis C. H. Maddock, Eva Hevia, William Clegg
Publikováno v: Angewandte Chemie International Edition. 57:187-191
While Fe(II) complexes have shown little promise in deprotonative metallation chemistry, pairing iron bis(amide) Fe(HMDS)2 with Na(HMDS) to form new sodium ferrate base [(dioxane)0.5·NaFe(HMDS)3] (1) enables regioselective mono and di-ferration (via
