Abstract
The electron-donating effect of a cyclopropyl group on an aromatic ring is expected to stabilize a cation center more efficiently than that of a phenyl group.'P2 This generalization led us to anticipate that a cyclopropyl group might exert a similar stabilizing influence on the cationic center N02H+(a protonated nitro group)? and we therefore undertook the investigation of the behavior of 2-cyclopropylnitrobenzene in a strong acid. 2- ...
