With AlCl3, dimerizes to give the complex of the otherwise unstable tetramethylcyclobutadiene, cycloaddition of which with dimethyl acetylenedicarboxylate gives a Dewar benzene: Synthesis, 139 (1971):
With a catalytic amount of AlCl3, hexamethyl Dewar benzene can be produced directly, with the 2-butyne also acting as the dienophile component: Org. Synth. Coll., 7, 256 (1990).
Reacts with chlorine to give 3,4-dichloro,1,2,3,4-tetramethylcyclobutene, a precursor of various cyclobutadienyl complexes: Org. Synth. Coll., 5, 370 (1973).
