Synthesis of N-aryl-N'-undecanoyl thiourea derivatives

The reaction of undecanoyl isothiocyanate with certain primary amines leads to the formation of the corresponding N-aryl-N'-undecanoylthiocarbamides. The above-mentioned isothiocyanates were obtained in situ by reaction of undecanoyl chloride with KSCN. The new compounds were characterised by spectroscopic methods data (IR, 1 H-NMR and 1 3 C-NMR).
