Synthesis and biological activities of some new 2-arylamino-4-fluoroarylthiazoles

Twenty-one new 2-arylamino-4-fluoroarylthiazoles have been synthesized by the condensation of the appropriate arylthiourea with the corresponding fluorophenacylbromide in ethanol. These new compounds have been characterized by elemental analysis and spectral studies. Some representative compounds have been screened for various biological activities viz. insecticidal, virucidal, bactericidal, fungicidal, herbicidal and antiarthritic.
