    摘要: The method provides nitro compounds at a high conversion and selectivity by nitrating substrates under comparatively mild conditions in the absence of catalysts. Organic substrates are nitrated using no catalysts or ozone, but using (1) at least one nitrogen compound selected from N.sub.2 O or NO and oxygen. It is advantageous for the nitration reaction to employ a nitrogen compound obtained by a reaction of the nitrogen compound with oxygen, particularly a nitrogen oxide comprising N.sub.2 O.sub.3 as a main component. Additionally, organic substrates are nitrated using (2) NO.sub.2. The substrates include a compound having a methine-carbon atom, and a compound having a methyl group or methylene group in an adjacent position to an aromatic ring.

    摘要: An aromatic compound (C) is reacted with carbon monoxide (D) and molecular oxygen (E) in the presence of a palladium compound catalyst (A) and a catalyst (B) and thereby yields a aromatic carboxylic acid corresponding to the aromatic compound (C) except with one or more carboxyl groups bonded to its aromatic ring. The catalyst (B) contains a heteropolyacid or a salt thereof (B1) or a mixture of oxo acids and/or salts thereof (B2), and the mixture (B2) contains, as a whole, one of P and Si and at least one selected from V, Mo and W.

    摘要: A malic acid or oxalacetic acid derivative is represented by the following formula (1): wherein ring Z is an alicyclic carbon ring; each of Ra and Rb is independently a hydrogen atom, a metal atom, or an organic group; and Y is a hydroxyl group or an oxygen atom, where ring Z is a bridged carbon ring or a monocyclic carbon ring having eight or more members when Y is an oxygen atom. The alicyclic carbon ring includes, for example, cyclooctane ring and adamantane ring. This compound is a novel malic acid derivative having an alicyclic group bonded to a carbon atom at the 3-position, or a novel oxalacetic acid derivative having a specific alicyclic group bonded to a carbon atom at the 3-position.
