| titleOfInvention | Production of 3,3' -or 3,4'-diaminobenzophenone |
| abstract | PURPOSE: To produce the titled compound useful as a raw material of agricultural chemicals and pharmaceuticals, an intermediate of dyes, etc., in high yield, by reducing a benzophenone compound with formic acid or a formic acid salt in the presence of palladium catalyst, and dechlorinating the reduction product. n CONSTITUTION: The objective 3,3'- or 3,4'-diaminobenzophenone is produced by reducing the benzophenone compound of formula (X is Cl substituted to 4 or 6 position; Y is H or Cl, when Y is H, the position of the amino group is 3' or 4', and when Y is 4'-Cl, the amino group is 3') with formic acid or a formic acid salt in the presence of a palladium catalyst (e.g. palladium activated carbon), and dechlorinating the reaction product. The amount of the catalyst is 0.01W10wt% based on the benzophenone compound used as the raw material. The formic acid or the formic acid salt is used in the form of an aqueous solution, and its amount is slight excess to the stoichiometric amount. The solvent is usually the one miscible with water, e.g. alcohol. The reaction is carried out usually at 30W110°C. n COPYRIGHT: (C)1985,JPO&Japio |
