| titleOfInvention | Imidomethyl derivatives of phthalocyanines |
| abstract | The invention comprises tetraazaporphines of the formula <FORM:0695523/IV (c)/1> in which Ar is an o-arylene radical, Me represents two H atoms or one atom of a divalent metal having a co-ordination number of 4 to 6 and at least one Ar is substituted by <FORM:0695523/IV (c)/2> in which R is 1,2-divalent radical. The products are made by reacting phthalocyanines under anhydrous acidic conditions with (1) a hydroxymethyl imide of the formula <FORM:0695523/IV (c)/3> or (2) a mixture of sulphuric acid, paraformaldehyde and an imide of the formula <FORM:0695523/IV (c)/4> or (3) with an imidomethyl ether of the formula <FORM:0695523/IV (c)/5> In examples: (1) copper phthalocyanine is reacted with sulphuric acid, phthalimide, and paraformaldehyde, alone, or together with phosphorus pentoxide or oleum, in varying proportions; (2) copper phthalocyanine is reacted with sulphuric acid and bis-phthalimidomethyl ether; (3) copper phthalocyanine is reacted with N-hydroxymethylphthalimide, sulphuric or phosphoric acid, and phosphorus pentoxide; (4) copper phthalocyanine is reacted with N-hydroxymethylphthalimide, sulphuric acid, and acetic anhydride; (5) copper phthalocyanine is reacted with 4-nitrophthalimide, sulphuric acid, paraformaldehyde, and phosphorus pentoxide; (6) copper phthalocyanine is reacted with succinimide, sulphuric acid, and paraformaldehyde; (7) metal-free phthalocyanine is reacted with N-hydroxymethylphthalimide, phosphorus pentoxide, and phosphoric acid; (8) monochloro copper phthalocyanine is reacted with N-hydroxymethylphthalimide in sulphuric acid. The proportions used in the examples are such that varying numbers of substituents from one to eight per molecule of phthalocyanine are introduced. Iron, cobalt, nickel, tin, and copper phthalocyanines are also referred to. Other imides specified are glutarimide, b b 1-dimethylglutarimide, a a 1-dimethylglutarimide, maleic imide, methylmaleic imide, phenylsuccinimide, tetrahydrophthalimide, 4-chlorophthalimide, 3,5-dichlorophthalimide, 4-nitrophthalimide. |
