A microwave-assisted method for the synthesis of assymetrical fluoroazobenzenes is described. The method is environmentally friendly since it does not require the use of organic solvents. It is faster and gives better yields than other procedures reported. It has proven to be versatile to obtain different mono- and di- substituted fluoroazobenzenes that are not obtainable by other methods, such as photochemical synthesis. Fluoroazobenzenes have applications in non-linear optics, have been used as dyes, and are intermediates in the preparation of hydroxyfluoroazobenzenes, which have been evaluated as inhibitors of steroid biosynthesis.
