This paper reveals ambiphilic reactivity and radical methylation in a Bi(III) complex, indicating innovative ligand design could enable precise chemical transformations.
Key Points
The T-shaped Bi(III) center shows ambiphilic reactivity, allowing for both nucleophilic and electrophilic methylation.
Oxidative addition of mild electrophiles to the Bi(III) center is facilitated by ligand-centered two-electron oxidation.
Single-crystal X-ray crystallography and DFT analysis confirm the structural dynamics of Bi-centered methylation.
The redox-active ligand allows for controlled transfer of methyl groups, enhancing the utility of the Bi(NNN) complex.
