Abstract

Single and double dearomatization of pyridine rings was observed in Mn^I complexes with an N2S2 pyridinophane ligand via deprotonation of one or two CH₂ arms, respectively. In contrast to other N,S-donor pincer-like systems, the dearomatized (N2S2)Mn species were found to be stable, with the dearomatization being reversible.
