A Convenient Route to Heteronaphthacenes

Heteronaphthacenes 1 were prepared in two steps from 1,3-dihydrobenzo[c]thiophene 2,2-dioxide (4) and dienophiles 2 via convenient high-temperature Diels-Alder reactions.

Facile Construction of Furanoacenes by a Three-Step Sequence Going through Disilyl-exo-cyclic Dienes

Facile synthesis of various benzonaphthofurans was achieved by intramolecular hydroarylation of 1,4-disilyl-2-aryloxy-1,3-enynes followed by cycloaddition with arynes or alkenes and finally desilylaromatization. The three-step transformation can be operated sequentially in one-pot, providing with a range of furanoacenes easily and highly effectively.

Microwave-Promoted Pd-Catalyzed Synthesis of Dibenzofurans from Ortho-Arylphenols

ortho-Aryl phenols, synthesized via protecting group free Suzuki–Miyaura coupling of ortho-halophenols and arene boronic acids, undergo a cyclization to dibenzofurans via oxidative C–H activation. The reaction proceeds under microwave irradiation in short reaction times using catalytic amounts of Pd(OAc)2 without additional ligands.

OXYGEN-CONTAINING FUSED RING AMINE COMPOUND, SULPHUR-CONTAINING FUSED RING AMINE COMPOUND, AND ORGANIC ELECTROLUMINESCENT ELEMENT

A fused amine compound including a furan ring or a thiophene ring and an organic electroluminescence device employing the amine compound. The organic electroluminescence device includes a cathode, an anode, and one or more organic thin film layers which are disposed between the cathode and the anode. The organic thin film layers include a light emitting layer and at least one layer of the organic thin film layers includes at least one amine compound.
