  • Process for producing aromatic carboxylic acid
    Patent number: 5760288
    Abstract: Provided is a process for producing an aromatic carboxylic acid by oxidizing an aromatic compound having an alkyl group or a partially-oxidized alkyl group with a molecular-oxygen-containing gas in an aqueous medium, characterized in that a compound in which a transition metal is incorporated into a heteropoly-acid skeleton having a deficient structural moiety is used as a catalyst.In accordance with the present invention, the aromatic carboxylic acid can be produced efficiently at low costs.

  • 2-cyanopiperazine and method of producing the same
    Patent number: 5698697
    Abstract: 2-Cyanopiperazine represented by the following formula (1): ##STR1## or a salt thereof. The 2-cyanopiperazine can be produced by reacting a 2-halogenoacrylonitrile with ethylenediamine or by reacting a 2,3-dihalogenopropionitrile with ethylenediamine.The 2-cyanopiperazine is useful as an intermediate for medicaments, agricultural chemicals, etc., and optically active N-tert-butyl-2-piperazine carboxamide, which is useful as an intermediate in preparation of the HIV protease inhibitor indinavir, can be easily produced using the 2-cyanopiperazine.
