Significance

Terminal alkynes react with aryl bromides in water at ambient temperature in the presence of an amphiphilic nanomicelle-forming reagent PTS. The development of new processes using pure water as a solvent is quite important for the chemical industry, since they allow decreasing the amount of the produced wastes as well as the manufacturing costs of products.
