METHOD FOR PRODUCING TETRAKIS[TRIS(DIMETHYLAMINO)PHOSPHORANYLIDENEAMINO]PHOSPHONIUM CHLORIDE

摘要

PROBLEM TO BE SOLVED: To provide a method for safely/easily producing tetrakis[tris(dimethyamino)phosphoranylideneamino]phosphonium chloride in high yield and high selectivity on an industrial scale without the need of isolatedly handling phosphorus pentachloride. SOLUTION: The method for producing the tetrakis[tris(dimethyamino)phosphoranylideneamino]phosphonium chloride comprises the following process: Phosphorus trichloride and chlorine are reacted with each other in the presence of an aromatic hydrocarbon to form phosphorus pentachloride, subsequently in a condition of reaction mixture without isolation/refining of the phosphorus pentachloride, the phosphorus pentachloride in the reaction mixture and iminotris(dimethylamino)phosphorane are reacted with each other.
