Diels-alder reaction of isobenzofurans/cyclopentadienones with tetrathiafulvalene: Preparation of naphthalene, fluoranthene, and fluorenone derivatives

Diels-Alder reaction of 1,3-diarylbenzo[c]furan/cyclopentadienone with TTF followed by triflic acid mediated cleavage of the resulting adducts led to the formation of the respective 1,4-diaryl substituted naphthalenes, fluoranthenes, and fluorenones. The photophysical properties of representative diaryl-substituted hydrocarbons are also reported.

A Simple and Versatile Acetylene Equivalent in Diels-Alder Reactions

Allyl phenyl sulphone and cinnamyl p-tolyl sulphone underwent cycloaddition with tetraphenylcyclopentadienone, indanocyclone, 1,3-diphenylisobenzofuran, and tetraphenylcyclopentadiene to give the adducts with elimination of methyl phenyl sulphone and meth
