Isomers and isomerism in chemistry.

Isomerism is a chemical term that describes the accurance of compounds with the same kind and number of atoms in a molecule, but different arrangements of these atoms. This isomers have the same molecular formula, diffent structural formulae and different properties.

Two stereoisomeric molecules have the same constitution, ie the same structure, but differ in the spatial arrangement of individual atoms or molecular groups. For details, see also stereochemistry.

Constitution isomers differ - with the same number and type of atoms - in the order and arrangement of the particles and the bonds. Therefore there are two completely different chemical compounds.

Dynamic Stereochemistry of Chiral Compounds: Principles and Applications

In this book the reader is presented with a comprehensive overview of fundamental concepts of asymmetric synthesis along with in-depth discussion of strategies for the synthesis and stereoselective interconversion of compounds exhibiting central axial and planar chirality, numerous racemization and diastereomerization reactions.

Details of analytical methods are provided and discussed as well as topics relating to the design of fascinating topologically chiral assemblies and molecular technomimetic devices in the context of dynamic stereochemistry. Strategies and recent developments that address important synthetic challenges are presented and highlighted with hundreds of examples, applications and detailed mechanisms.
