Synthesis, structure and redox reactions of a new crowded benzodithiolium salt: first isolation and characterization of a stable dithiolyl radical with a 7π electron framework

Abstract

The molecular structure of the sterically crowded 3-(2,4,6-triisopropylphenyl)-1,2-benzodithiolium cation has been determined by crystallographic studies on the BF₄^– salt and the corresponding novel 1,2-dithiolyl radical with a 7π electron framework has been isolated by one-electron reduction.
