reaction conditions. The aqueous layer aer the work up was
treated with dilute HCl and the obtained benzoic acid was
analysed by GC-MS and 1H NMR (see ESI†). These experiments
were helpful to support the reaction mechanism.
In conclusion, a selective, controlled, cost effective, mild and
highly efficient procedure is developed for the formation of
synthetically important azobenzenes. The developed protocol
can be considered as environmentally friendly as it avoids use of
reducing agent and other additives and did not produce any
hazardous by-products as well. The reaction operation is simple
and easy to handle and it is suitable for large scale industrial
production. Importantly, signicant decrease in the yield of
