substrates for palladium-catalyzed C−F bond arylation using readily available palladium catalysts under both conventional heating and microwave conditions. Arylation occurs ortho to the nitro group offering a synthetic route to polyfluorinated 2-arylnitrobenzene systems. The regiochemistry of the arylation reactions suggests that there is a significant directing interaction between the nitro group and the incoming

A novel carbazole derivative represented by formula (1) in which two or more groups each having a specific structure, such as a carbazolyl group, are bonded to two or more of 2-, 3- and 4-positions of the carbazole derivative is useful as a material for organic electroluminescence devices. A material for organic electroluminescence devices including the carbazole derivative, an organic electroluminescence device employing the carbazole derivative, and an electronic equipment are described.
