1,3-Disubstituted triazenes 3 are oxidized with ten-butyl hypochlorite to N-chlorotriazenes 4, which at low temperatures with antimony pentachloride afford 1,3-diaza-2-azoniaallene salts 5 as reactive intermediates. Cations 5 undergo cycloadditions to one or both double bonds of 1,3-butadienes to fu
