Abstract: In this paper, ferrocenoyl isothiocyanate is synthesized for the first time.Without being separated, it reacts with various amines, such as heterocyclic amines, aliphatic amines with lower molecular weight, α-naphthyl amine and aromatic amines containing various substituted groups.Twenty one N-ferrocenoyl-N'-Ary (alkyl) thiourea derivatives have been obtained in good yields.They can be conveniently isolated and purified.At a low temperature (- 5-0℃), ferrocenoyl-isoth-iocyanate reacts with aqueous solutions of free amines (i.e.33% ethyl amine, 25% methyl amine) to form corresponding derivatives in fairly good yields.All the compounds have not been reported so far and their structures have been confirmed by elemental analysis, 1H NMRand IR.
