A highly site-selective, one-pot, sequential C–N and C–C bond forming process was developed, affording a carbazole-based skeleton that contains biphenyl and diarylacetylene cores. The success of this process is attributed to the use of fluorinated iodoarenes as the starting material, the fluorine group of which preferentially reacts with carbazole. The subsequent coupling of the intermediate iodinated

An object is to provide a light emitting element with low drive voltage which contains an organic compound and an inorganic compound. One feature of a light emitting element of the present invention is to include a layer containing a light emitting material between a pair of electrodes, in which the layer containing a light emitting material has a layer containing a carbazole derivative represented by General Formula (1) and an inorganic compound which exhibits an electron accepting property to the carbazole derivative represented by General Formula (1). With such a structure, the inorganic compound accepts electrons from the carbazole derivative, carriers are generated internally, and a drive voltage of the light emitting element can be reduced.
