In comparison to traditional organic synthesis, catalyst-free synthetic techniques provide several advantages and have been proved to be environmentally friendly. Here, a facile catalyst-free procedure for the synthesis of derivatives of diarylsulfonylureas was developed. The simple process involves reacting p-toluenesulfonyl isocyanate with various substituted primary amines in the presence of dichloromethane as the solvent at room temperature to produce the desired diarylsulfonylureas derivatives. Nine compounds with up to 94% yield have been synthesized successfully through this protocol. These products' structures were characterised using a variety of techniques, including fourier-transform infrared spectroscopy, mass spectroscopy, nuclear magnetic resonance spectroscopy, physical analysis, and melting point. Overall, this method has many benefits, including convenient room temperature synthesis, a straightforward workup procedure, rapid reaction times, and quantifiable reaction yields.
