Synthesis and antimicrobial activity of N-(substituted)-N′-[1,2,4, 8,10,11-hexachloro-6-oxido-12H-dibenzo(d,g)(1,3,2)-dioxaphosphocin-6-yl]ureas
Substituted dibenzo dioxaphosphocin-6-yl ureas were synthesized by reacting hexachlorophene (4) with different carbamidophosphoric acid dichlorides (3) in the presence of triethylamine in dry toluene at 45-50 °C. Their IR, 1H, 13C and 31P NMR spectral data is discussed. These compounds were found to possess good antimicrobial activity.
