Diels-Alder reaction of tetraarylcyclopentadienones with benzo[: B] thiophene S, S-dioxides: An unprecedented de-oxygenation vs. sulfur dioxide extrusion

Diels-Alder reaction of tetraarylcyclopentadienones with benzo[b]thiophene dioxides in xylenes at reflux led to the formation of tetra aryl-substituted dibenzothiophene as well as penta aryl-substituted benzene analogues depending on the influence of aryl substituents present on cyclopentadienones. The intermediate dihydrodibenzothiophene-dioxides underwent aromatization either through de-oxygenation or extrusion of sulfur dioxide to furnish substituted dibenzothiophenes or benzenes.

ORGANIC COMPOUNDS AND ORGANIC ELECTRO LUMINESCENCE DEVICE COMPRISING THE SAME

The present invention relates to a novel compound and an organic electroluminescent device comprising the same. A compound according to the present invention is used for an organic layer, preferably a hole injecting layer, a hole transporting layer, a hole transport auxiliary layer, a light emitting layer, an electron transport layer, or an electron injecting layer of the organic electroluminescent device, thereby being able to improve luminous efficiency, driving voltage, lifespan and the like of the organic electroluminescent device.COPYRIGHT KIPO 2019

Palladium-catalyzed three-component domino reaction for the preparation of benzo[b]thiophene and related compounds

A simple and efficient palladium-catalyzed three-component domino reaction of bromothiophenes with internal alkynes has been developed to produce benzo[b]thiophenes in moderate to good yields. The Royal Society of Chemistry 2011.

Fused ring construction around pyrrole, indole, and related compounds via palladium-catalyzed oxidative coupling with alkynes

(Chemical Equation Presented) The selective synthesis of 1,2,3,4-tetrasubstituted carbazoles can be performed effectively through the palladium-catalyzed oxidative coupling reactions of N-substituted indoles or their carboxylic acid derivatives with alkyn

Cycloaddition of benzo[b]thiophene-S,S-dioxide - A route to substituted dibenzothiophenes and dibenzothiophene S,S-dioxides

Benzo[b]thiophene S,S-dioxide can be transformed by cycloaddition with tetraarylthiophene S-oxides to tetraaryldibenzothiophene S,S-dioxides. An analogous cycloaddition of benzo[b]thiophene S,S-dioxide, albeit at higher temperatures, leads directly to tet
