NMR and computational studies of the chemical reduction of [2.2]paracyclophane: formation of dianionic p-xylenyl oligomers.
Reaction of [2.2]paracyclophane with K/Na alloy in THF gives a p-xylylenyl dianion together with its dimer and trimer which are relatively stable at low temperatures; at ambient temperatures further polymerization takes place.
