摘要： A process of reducing unsaturated organic compounds efficiently by using industrially inexpensive and easily handleable trichlorosilane as the reducing agent to thereby obtain the corresponding reductants; and reducing agents. Specifically, a process for the preparation of reductants of unsaturated organic compounds, characterized by conducting the reduction of an unsaturated organic compound by mixing the compound with trichlorosilane in the presence of a compound capable of reacting with trichlorosilane to give a five-coordinate silicon complex, e.g., N-formylated secondary amine having 3 or more carbon atoms; and reducing agents consisting of specific silicon complexes.

摘要： A process for producing an aliphatic dicarboxylic acid compound in which an alicyclic secondary alcohol compound or alicyclic ketone compound in which at least one methylene group has been bonded to the hydroxy-bonded carbon atom or to the carbon atom as a member of the carbonyl group is oxidized with a nitrite or nitrate in the presence of trifluoroacetic acid, characterized in that the reaction is conducted while regulating the amount of water present in the system so as to be 5 mass% or smaller based on the total amount of the trifluoroacetic acid and the water.
