| titleOfInvention | Production of aromatic urea compound |
| abstract | PURPOSE: To obtain the title compound safely, readily and in high yield without requiring facilities for high pressure by reacting an aromatic amine with an N-formyl aromatic amine compound in the presence of a catalyst consisting essentially of a compound containing a platinum group under a mild condition. n CONSTITUTION: An aromatic amine such as aniline shown by formula I (R 1 is H, Cl, CH 3 , OCH 3 , etc.) is reacted with an N-formyl aromatic amine compound such as formanilide shown by formula II (R 2 =R 1 ) preferably in a solvent such as mesitylene in the presence of a compound such as an organometallic compound, e.g. RuCl 2 (PPh 3 ) 3 (PPh 3 is triphenylphosphine) containing a platinum group metal and a ligand such as CO or phosphine or an organic group at 30-300°C preferably 120-200°C under normal pressure for several minutes to several hours to give the objective compound such as N,N'-diphenlurea shown by formula III useful as an intermediate for producing herbicides, plant growth regulators and urethane. The above-mentioned method has a minimum cost of facilities. n COPYRIGHT: (C)1992,JPO&Japio |
