The dienic nature of the aromatic pi-system in 1,4-diphosphinines remains largely unexplored to this day due to a lack of facile and efficient synthetic protocols. Recently reported stable, tricyclic 1,4-diphosphinines were used to explore the thermal reactivity of the pi-system towards an array of dienophiles in [4 pi+ 2 pi]-and, for the first time, in [4 pi+ 2 sigma]-type cycloaddition reactions.
