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.

Regioselective Suzuki-Miyaura Cross-Coupling Reactions of the Bis(triflate) of 1,4-Dihydroxy-9 H -fluoren-9-one

1,4-Diaryl-9H-fluoren-9-ones were prepared by regioselective Suzuki-Miyaura cross-coupling reaction of the bis(triflate) of 1,4-dihydroxy-9H-fluoren-9-one. The reactions proceeded with excellent site selectivity. The first attack occurs at position 1, due to electronic reasons.
