Reversible Redox Ligand-Centered Reactivity in 2,6-Bisiminopyridine Aluminum Systems

We report the synthesis of cationic 2,6-bisiminopyridine organoaluminum complexes, [(BIP)­AlR2]+, as stable BArF 4 – or PF6 – salts, and their reversible single-electron reduction into well-defined paramagnetic species, [(BIP·)­AlR2]. Four redox couples, [(BIP)­AlR2]+/0, have been fully characterize...
