A new one-pot synthesis of C2-hydroxypropyl-substituted imidazolinium salts via the ringopening of tetrahydrofuran (THF) with N,N′-disubstituted diamines has been developed. Preliminary studies of the reaction mechanism suggest the CO2-promoted oxidative ringopening of THF followed by Hg(II)-mediated oxidation of an imidazolidine intermediate. These novel C2-substituted imidazolinium salts have shown
