The present invention discloses a series of novel OLEDs (phenothiazine) compound and its new synthetic method in under the nitrogen atmosphere, will be double-halide compound, primary amine, palladium compound, phosphine, alkali may be dissolved in the organic solvent, heating and stirring the reaction, extraction, drying, concentration, purification, to prepare a series of phenoxazine or phenothiazine compound. The invention involves the oxygen (sulfur) nitrogen compound synthesis technology field, in particular to a phenoxazine (phenothiazine) the preparation method of compound. The invention through palladium-catalyzed double-halide compound with the primary amine N-position and double-aromatise synthetic OLEDs (phenothiazine) compound, simple synthesis steps, mild reaction conditions, operation is simple and easy, the product yield as high as 99%, but also the applicable substrate a wide range, for the OLEDs (phenothiazine) compound synthesis provides a new train of thought, in the organic synthesis methodologically has great significance.
