Cover Feature: Non‐Coordinated Phenolate Anions and Their Application in SF6 Activation (Chem. Eur. J. 21/2021)

The non‐coordinated phenolate anion ([H5C6‐O]− is easily accessible by deprotonation of phenol with the superbasic perethyl tetraphosphazene Schwesinger base, while monophosphazenes only deliver the hydrogen‐bonded phenol–phenolate adduct. Hydrogen bonding influences the electron donation and brings...

Description
Summary:The non‐coordinated phenolate anion ([H5C6‐O]− is easily accessible by deprotonation of phenol with the superbasic perethyl tetraphosphazene Schwesinger base, while monophosphazenes only deliver the hydrogen‐bonded phenol–phenolate adduct. Hydrogen bonding influences the electron donation and brings about lowered redox potentials. Synthesized electron‐rich non‐coordinated phenolates featuring strong redox potentials are capable for the SF6 activation and lead to pentafluorosulfanide [SF5]− salts.
