A three-component reaction between 1,2-phenylenediamine, ferrocenecarbaldehyde, and isocyanides in the presence of a catalytic amount of p-toluenesulfonic acid for the synthesis of 3,4-dihydroquinoxalin-2-amine derivatives containing a ferrocene unit is reported. This approach is an effective procedure because the products have a broad spectrum of biological and pharmacological activities such as insecticide, fungicide, herbicide, anthelmintic, antibacterial, antimycobacterial, antiprotozoal, anticancer and antibiotic properties.
