Hydrogen Transfer Reactions, 17 1) . — Electron‐Transfer‐Induced Aromatization of 1,4‐Dihydronaphthalene by Tris(4‐bromophenyl)aminiumyl Ions The first step in the aromatization of 1,4‐dihydronaphthalene ( 1 ) by the radical cation 2 of tris(4‐bromophenyl)amine ( 3 ) is a rapid electron transfer in an equilibrium completely shifted to the side of the substrates. The deprotonation of the radical cation 7 of 1,4‐dihydronaphthalene is rate‐determining as shown by both cyclovoltagrams and isotope effects of deuterated hydrogen donors.
