1,4-Dithiin annelated with bicyclo[2.2.2]octene units: experimental and theoretical evidence for the aromaticity in 1,4-dithiin dication
Abstract
1,4-Dithiin dication annelated with bicyclo[2.2.2]octene units was generated by the two-electron oxidation of the neutral dithiin and found to be aromatic based on the results of NMR measurements and theoretical calculations.
