Patent number: 5331099Abstract: A process for preparing p-nitroaromatic amides is provided which comprises contacting an amide and nitrobenzene in the presence of a suitable solvent system, and reacting the amide and nitrobenzene in the presence of a suitable base and a controlled amount of protic material at a suitable temperature in a confined reaction zone. The p-nitroaromatic amides of the invention can be reduced to p-aminoaromatic amides. In one embodiment, the p-aminoaromatic amide is further reacted with ammonia under conditions which produce the corresponding p-aminoaromatic amine and the amide starting material which can be recycled or with water in the presence of a suitable basic or acidic catalyst under conditions which produce the corresponding p-aminoaromatic amine and the acid or salt thereof corresponding to the amide starting material. In another embodiment, the p-aminoaromatic amine is reductively alkylated to produce alkylated p-aminoaromatic amine.Type: GrantFiled: April 16, 1993Date of Patent: July 19, 1994Assignee: Monsanto CompanyInventors: Michael K. Stern, James K. Bashkin
