PURPOSE:To provide the novel phthalocyanine derivative useful for pigments, dyestuffs, and further for functional materials such as organic photoconductive materials and photomemorizing materials. CONSTITUTION:The phthalocyanine derivative of formula I (M is a metal atom, its oxide or its halide, but a case in which M is Cu Ge-Cl2, or Sn-Cl2 is excluded), e.g. tetrakis (trifluoromethyl) phthalocyanine tin. The compound of formula I, especially a compound of formula II which is the compound of formula I in which trifluoromethyl is (R)n (R is an alkyl, haloalkyl, alkoxy, etc.; (n) is 0-4) is obtained by reacting an aromatic dichloride of formula II in the presence of a catalyst comprising a Pd compound and a phosphine compound, reacting the produced phthalimide compound of formula IV with ammonia, further reacting the produced compound of formula V with oxyphosphorus chloride, and finally reacting the produced phthalonitrile compound of formula VI with a metal oxide or metal halide in the presence of a basic catalyst. |
