This reaction involves the formation of a C-N bond under transition Metal-free conditions. Metal-free synthesis of “phenothiazine chalcone N-based heterocycle” by different derivatives of phenothiazine chalcone and 2-Amino pyridine, iodine, NH4OAc promoted reaction offers a novel route in the synthesis of “phenothiazine chalcone N-based heterocycle” in good to excellent yield.

The metal sulfide nanoparticles were characterized using powder X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), thermogravimetric analysis (TGA), field emission scanning electron microscopy (FE-SEM), energy dispersive X-ray analysis (EDXA), transmission electron microscopy (TEM) and diffuse reflectance spectroscopy (DRS). The band gaps for indium sulfide nanoparticles and silver indium sulfide nanoparticles are 2.2 eV and 2.0 eV, respectively. Dyes such as rhodamine B and methyl orange were successfully photodegraded using the metal sulfide nanoparticles as catalyst. Adsorption of congo red was also done using metal sulfide nanoparticles as the adsorbent.

Diazoketones have been investigated for almost a century, and the numerous new advancements published so far show that there is still a lot of intriguing chemistry to be discovered in these compounds. The fact that they have such a wide range of applications in medical and photometry was a major factor in their selection of this project. The most appealing application that motivated us to synthesize α-diazoketones was the cycloaddition reaction of ketene (produced in the thermal or photochemical reaction of α-diazoketones) with alkenes/alkynes.
