Dimedone is an organic compound with the formula (CH3)2C (CH2)2(CO)2(CH2). Classified as a cyclic diketone, it is a derivative of 1,3-cyclohexanedione. It is a white solid that is soluble in water, as well as ethanol and methanol. It once was used as a reagent to test for the aldehyde functional group.
trans-1,2-Diaminocyclohexane is an organic compound with the formula C 6 H 10 (NH 2) 2. This diamine is a building block for C2 -symmetric ligands that are useful in asymmetric catalysis. [1] A mixture of all three stereoisomers of 1,2-diaminocyclohexane is produced by the hydrogenation of o -phenylenediamine.
1,2-Diaminocyclohexane (DACH) is an organic compound with the formula (CH 2) 4 (CHNH 2) 2. It is a mixture of three stereoisomers: cis -1,2-diaminocyclohexane and both enantiomers of trans -1,2-diaminocyclohexane. The mixture is a colorless, corrosive liquid, although older samples can appear yellow. It is often called DCH-99 and also DACH.

Structural isomer. In chemistry, a structural isomer (or constitutional isomer in the IUPAC nomenclature [ 1 ]) of a compound is another compound whose molecule has the same number of atoms of each element, but with logically distinct bonds between them. [ 2 ][ 3 ] The term metamer was formerly used for the same concept. [ 4 ]
2 c 6 h 12 + o 2 → 2 c 6 h 11 oh This process coforms cyclohexanone , and this mixture ("KA oil" for ketone-alcohol oil) is the main feedstock for the production of adipic acid . The oxidation involves radicals and the intermediacy of the hydroperoxide C 6 H 11 O 2 H. Alternatively, cyclohexanol can be produced by the hydrogenation of phenol :
trans -but-2-ene. Cis–trans isomerism, also known as geometric isomerism, describes certain arrangements of atoms within molecules. The prefixes " cis " and " trans " are from Latin: "this side of" and "the other side of", respectively. [ 1 ] In the context of chemistry, cis indicates that the functional groups (substituents) are on the same ...
IUPAC nomenclature of organic chemistry. In chemical nomenclature, the IUPAC nomenclature of organic chemistry is a method of naming organic chemical compounds as recommended [1][2] by the International Union of Pure and Applied Chemistry (IUPAC). It is published in the Nomenclature of Organic Chemistry (informally called the Blue Book). [3]
