3. SbPh, 1,1,2,2-TetrachloroethaneSystem. The reaction of SbPh, (0.05 M) and 1,1,2,2-tetrachloroethane in the presence of aluminum chloride resulted in an EPR spectrum (Figure S6a12) identical with that of the dibenzo[a,c]triphenylene radical cation in SbC15-CH2C12 solution.16 Proton hyperfine coupling constants of 0.60, 2.00, 2.27, and
