A reaction of 3-arylcyclobutanones with anthracene in the presence of TiCl4 gave 14-aryl-9,10-dihydro-9,10-butanoanthracen-12-ones as a formal [4 + 4] cycloadduct of anthracenes with a C4 unit formed by cleaving the more substituted C2C3 bond of cyclobutanones. On the other hand, activation of 3-arylcyclobutanones with TfOH in the absence of nucleophiles gave 2-tetralones with skeletal rearrangement
