- Synthesis of triazenes of n-heterocycles mediated by resin immobilized diazonium ions
-
Diazonium ions were prepared from aromatic amines and immobilized in cation exchange resin support and used for the synthesis of triazenes of piperidine and morpholine in a solid phase synthesis. Immobilization is an excellent technique for the stabilization of diazonium ions and can be preserved in the solid state. Using resin immobilized diazonium ions, triazene synthesis is carried out in the absence of acids thereby increasing the yield of the product and simplifying work up.

- Sulfide synthesis through copper-catalyzed C-S bond formation under biomolecule-compatible conditions
-
We report here an efficient and mild method for constructing C-S bonds. The reactions were carried out with Na2S2O3 as a sulfurating reagent, CuSO4 as a catalyst, and water as solvent without any surfactant. The products were achieved in moderate to excellent yields at room temperature under air. Notably, this reaction is compatible with various biomolecules including amino acids, oligosaccharides, nucleosides, proteins, and cell lysates. This journal is

- Thermal cis-to-trans isomerisation of triazene dyes in doped polymer films
-
The kinetics of the thermal conversion of the cis to the trans isomeric forms of 1,3-diphenyltriazene and 1-phenyltriazenes derived from cyclic amines were determined in both poly(methyl methacrylate) and polystyrene doped films in the glassy state, using
