phthalonitriles 1, 2, or 4 (R1, R3, R4=H, R2=NO2) (4 equivs.) with Et2NOH (8 equivs.) in the presence of a metal salt MCl2 (M=Zn, Cd, Co, Ni) (1 equiv.) in n-BuOH or without solvent results in the formation of metallated phthalocyanine species (9–17). Upon refluxing in freshly distilled dry chloroform, phthalonitrile 1 or its substituted analogues 2, 3 or 5 (R1–R4=F) (1 equiv.) react with N,N-diethylhydroxylamine
