Conspectus Cyclopropenium ions are the smallest class of aromatic compounds, satisfying Hückel’s rules of aromaticity with two π electrons within a three-membered ring. First prepared by Breslow in 1957, cyclopropenium ions have been found to possess extraordinary stability despite being both catio...
