TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Process: 4-trifluoromethyl phthalonitrile of formula (1') is synthesized using 4-halogen phthalonitrile where halogen is chlorine, bromine, or iodine, and Yagorofusuki reagent as perfluoroalkylation agent. 3-trifluoromethyl phthalonitrile of formula (2') is synthesized using 3-halogen phthalonitrile where halogen part is chlorine, bromine, or iodine, and Yagorofusuki reagent as perfluoroalkylation agent. 4,5-di(trifluoromethyl) phthalonitrile of formula (3') is synthesized using 4,5-di(halogen) phthalonitrile where halogen part is chlorine, bromine, or iodine, and Yagorofusuki reagent as perfluoroalkylation agent. 3,6-di(trifluoromethyl) phthalonitrile of formula (4') is synthesized using 3,6-di(halogen) phthalonitrile where halogen part is chlorine, bromine, or iodine, and Yagorofusuki reagent as perfluoroalkylation agent. beta -tetra(trifluoromethyl) phthalonitrile of formula (5') is synthesized using 4-trifluoromethyl phthalonitrile as 4-perfluoroalkyl phthalonitrile. alpha -tetra(trifluoromethyl) phthalocyanine is synthesized using 3-trifluoromethyl phthalonitrile as 3-perfluoroalkyl phthalonitrile. beta -octa(trifluoromethyl) phthalocyanine derivative of formula (7') is synthesized using 4,5-di(trifluoromethyl) phthalonitrile as 4,5-di(perfluoroalkyl) phthalonitrile. alpha -octa(trifluoromethyl) phthalocyanine derivative of formula (8') is synthesized using 3,6-di(trifluoromethyl) phthalonitrile as 3,6-di(perfluoroalkyl) phthalonitrile. EXAMPLE - In a nitrogen substituted test tube, 30 mg 3-trifluoromethyl phthalonitrile was dissolved. 6.9 mg zinc chloride was dissolved in 1 ml N,N-dimethylamino ethanol then heated and stirred overnight at 140 degrees C. The composition was cooled to room temperature, saturated aqueous ammonium chloride was added and ethyl acetate extracted 3 times. The organic layer was dried after washing using sodium sulfate then purified by silica gel column chromatography to obtain 23 mg alpha -tetra(trifluoromethyl) zinc phthalocyanine.
