✦ Synopsis

• hydrocarbon cations have been the focus of attention ever since tropylium (Tr + ) was predicted to be highly stable. [1] It fulfills Hückels rule and is the most common textbook example for aromaticity after benzene. However, the rivalry with its energetically close-lying isomer, benzylium (Bz + ), still poses diverse challenges (Scheme 1). For instance, physical
