Abstract
First indirect evidence for the formation of a radical cation of 1,8-b is(dimethylamino)naphthalene (''proton sponge'') in reactions with HNO 3, HNO2, NO2, and I-2 has been obtained. In all cases, the products of reaction of the radical cation with nucleophiles and/or its dimer, 4, 5,4',5'-tetrakis(dimethylamino)-1,1'-binaphthyl, have been isolated. 4 -Chloro-1,8-bis(dimethylamino)naphthalene has been regioselectively sy nthesized in high yield.
