An environmentally friendly approach to the green synthesis of azo dyes in the presence of magnetic solid acid catalysts

A solvent-free, efficient and green approach for the synthesis of azo dyes has been developed by the diazo coupling reactions of aromatic amines with β-naphthol in the presence of sulfonic acid functionalized magnetic Fe3O4 nanoparticles (Fe3O4@SiO2-SO3H) by a grinding method at room temperature. This green methodology aims to overcome the limitations and drawbacks of the previously reported methods such as low temperature, use of acids, alkalis and toxic solvents, instability of diazonium salts at room temperature, modest yields, and long reaction times. Moreover, the attractive advantages of the process include mild conditions with excellent conversions, simple product isolation process, inexpensive procedure and recyclability of the magnetic catalyst.

(13)C NMR and X-ray Structure Determination of 1-(Arylazo)-2-naphthols. Intramolecular Proton Transfer between Nitrogen and Oxygen Atoms in the Solid State

The tautomeric reaction involving a single proton transfer in 1-(phenylazo)-2-naphthol and its 4'-methoxy, ethoxy, and N,N-dimethylamino derivatives has been investigated with variable-temperature solution and high-resolution solid-state (13)C NMR spectroscopy.Crystal structures of the parent unsubstituted compound and the 4'-N,N-dimethylamino derivative have been determined.All of these compounds undergo a fast proton exchange on the NMR time scale between the tautomeric azo and hydrazone forms in both solution and the crystalline phase.Equilibrium compositions inthe solid materials are similar to those measured in solution.Crystals of 1-(phenylazo)-2-naphthol are monoclinic, a = 27.875 (7), b = 6.028 (2), c = 14.928 (5) Angstroem, β = 103.57 (2)0, the space group is C2/c with Z = 8, and the structure at 213 K was refined to an R factor of 0.0414 on 1082 observed reflections.Crystals of 1-(azo)-2-naphthol are monoclinic, a = 7.604 (1), b = 7.970 (3), c = 24.381 (7) Angstroem, β = 99.33 (2)0, the space group is P21/c with Z = 4, and the structure at 193 K was refined to an R factor of 0.0405 on 1522 observed reflections.
