Newman projection. A Newman projection is a drawing that helps visualize the 3-dimensional structure of a molecule. [1] This projection most commonly sights down a carbon-carbon bond, making it a very useful way to visualize the stereochemistry of alkanes. A Newman projection visualizes the conformation of a chemical bond from front to back ...

Infobox references. 1,2-Diphenyl-1,2-ethylenediamine, DPEN, is an organic compound with the formula H 2 NCHPhCHPhNH 2, where Ph is phenyl (C 6 H 5 ). DPEN exists as three stereoisomers: meso and two enantiomers S,S- and R,R-. The chiral diastereomers are used in asymmetric hydrogenation. Both diastereomers are bidentate ligands.
Infobox references. (E)-Stilbene, commonly known as trans-stilbene, is an organic compound represented by the condensed structural formula C 6 H 5 CH=CHC 6 H 5. Classified as a diarylethene, it features a central ethylene moiety with one phenyl group substituent on each end of the carbon–carbon double bond.
