Some novel benzoquinoline based heterocyclic monoazo dyes were derived by the diazotization of 1H-benzo[g]pyrazolo[3,4-b]quinoline-3-ylamine with various Ph pyrazolone as coupling components. All the heterocyclic monoazo dyes were characterized by elemental analyses and various spectral data (FT-IR, UV-Vis, 1H NMR and 13C NMR), and their 3D model structures were predicted through B3LYP/6-31G(d,p) method. The dyeing performance on polyester fibers inferred that all the dyes gave moderate to excellent fastness properties on fiber. In addition, colorimetric studies of synthesized dyes were discussed.

The construction of C-S bond is considered as an important protocol in organic transformations. An innovative strategy for CuI-catalyzed sulfenylation of 1-aryl-3-alkyl-1H-pyrazol-5(4H)-ones have been developed using elemental sulfur as the sulfur source. This procedure provides a useful and direct approach for the assembly of a wide range of structurally diverse 4-sulfenyl pyrazolones with moderate to excellent yields from simple and readily available starting materials. This method might be potentially applicable to large scale production, and it enriches current sulfenylation methods.
