Hydration reaction of tetracationic salt of [5]radialene bearing quintuple 4,5‐benzo‐1,3‐dithiol‐2‐ylidenes provided some unforeseen oxygen adducts: a transannular dicationic salt linked by oxygen atom; a tetrathiafulvalene vinylogue with 1,4‐dithiine‐2( 3H )‐one moieties; and a π‐extended tetrathiafulvalene with cyclopentenone core. The nucleophilic addition of H 2 O to [5]radialene depends on the structural feature of the π‐conjugated polycationic [5]radialene scaffold. More information can be found in the Full Paper by T. Shirahata, Y. Misaki, et al. on page 4984.
