The radical cation formed by mesylate heterolysis from the 1, 1-dimethyl-7, 7-diphenyl-2- mesyloxy-6-heptenyl radical was studied in several solvents. Computational results suggest that the initially formed acyclic radical cation is a resonance hybrid with partial positive charge in both double bonds of 1, 1-diphenyl-7-methyl-1, 6-octadiene (10). Thiophenol trapping was used as the competing reaction for kinetic determinations. The acyclic ...
