Elucidation of Reaction Mechanisms - Investigation of Stereochemistry

Investigation of the Stereochemistry

The mechanism of a reaction often leads to only a certain stereochemical course. As a result, only a small selection or even only one of the conceivable stereoisomers is formed. However, other reactions do not follow mechanisms that restrict the stereochemical variety of the products in any way.

Hint
Therefore, important aspects of the reaction mechanism can be derived from the type and variety of stereoisomers that are formed in a reaction.
Example

In SN2 reactions, for example, the stereochemistry of the product is restricted to a certain stereoisomer, according to the type of transition state.
