1 3-(4-Acetylphenyl)-(2-methyl)-2-chloro(bromo, thiocyanato)propanamides have been obtained via copper catalytic anionarylation of acrylic and methacrylic acids amides by 4-acetylphenyldiazonium salts. 5-(4-Acetylphenyl)substituted 2-aminothiazol-4(5H)-ones were synthesized by cyclisation of thiocyanatoamides. All synthesized compounds were tested for their antibacterial and antomycotic activity.
