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 C 2-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.

Methylcyclohexane(cyclohexylmethane) is an organic compoundwith the molecular formula is CH3C6H11. Classified as saturated hydrocarbon, it is a colourless liquidwith a faint odor. Methylcyclohexane is used as a solvent. It is mainly converted in naphtha reformersto toluene.[4]
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 -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 ...
1,2-Dimethylcyclopropane is a cycloalkane consisting of a cyclopropane ring substituted with two methyl groups attached to adjacent carbon atoms. [1] It has three stereoisomers, one cis -isomer and a pair of trans - enantiomers, which differ depending on the orientation of the two methyl groups. As with other cyclopropanes, ring tension results ...
