The subject invention relates to a catalyst comprises 1-75% of iron oxide, 1-10% of titanium metal oxide and the balance being attapulgate useful for the preparation of alkylated aromatic amines.

Process for the preparation of a new catalyst useful for producing

The present invention relates to a process for the preparation of alkylated aromatic amines which comprises reacting an aromatic amine selected from aniline, toludine, xylidine, N-methyl aniline, N-ethyl aniline, m-ethyl aniline, p-ethyl aniline, o-ethyl aniline with a primary or secondary alcohol selected from ethanol, methanol, isopropyl alcohol in the presence of attalpulgite impregnated with combination of iron oxide and oxides selected from transition metals of the periodic table as a catalyst prepared by the method described and claimed in our co-pending U.S. patent application Ser. No. 09/047,718 at atmospheric pressure and at a temperature in the range of 300-400.degree. C. and recovering the desired amine by conventional methods.

Process for producing alkylated aromatic amines with high selectivity

The present invention is drawn to complexes of dibenzyl-organotin compounds having nitrogen or sulfur containing heterocyclic ligands. Said complexes are useful as cytotoxic agents.
