Intermolecular cycloaddition of the bifunctional tetrachlorotribenzene 1 results in higher Diels–Alder oligomers of benzene ( 2 ), of which the linear and an angular hexamer ( n =1) were characterized. The oligomers decompose above 110°C through stepwise extrusion of benzene and tetrachlorobenzene.
