DOI: 10.1021/acs.inorgchem.4c02664
Abstract: We report the synthesis of cationic 2,6-bisiminopyridine organoaluminum complexes, [(BIP)AlR2]+, as stable BArF4– 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 characterized through… read more here.

Abstract: The novel iminoquinone N-(2,6-dibromophenyl)-4,6-di-tert-butyl-2-imino-o-benzoquinone (Briq), with electron-withdrawing and only mildly bulky 2,6-dibromophenyl substituents, is metalated by the iridium(I) complex {(coe)2IrCl}2 to give an inseparable mixture of (Briq)2Ir, (Briq)2IrCl, and (Briq)2IrCl2. This mixture can be funneled… read more here.
