Tutorial Stereochemistry of Reactions

Let us first repeat the essential features of handling the stereochemistry of molecular structures by permutation group theory  

The numbering of the skeleton can be fexed arbitrarily, but thereafter it must always be kept the same, 

A reference isomer is defined as the structure where ligand number I is on skeleton position 1, ligand no. 2 is on skeleton position 2, etc. This reference isomer obtains the descriptor + 1). 

It can easily be verified that the nomenclature factor, n. can be calculated according to Eq. (9) 

The representation of a chemical reaction should include the connection table of all participating species starting materials, reagents, solvents, catalysts, products) as well as Information on reaction conditions (temperature, concentration, time, etc.) and observations (yield, reaction rates, heat of reaction, etc.). However, reactions are only Insuffclently represented by the structure of their starting materials and products,
