Question

What is a stereospecific reaction, but not necessarily enantioselective?

Answer 1

Stereospecificity is the property of a reaction mechanism that leads to different stereoisomeric reaction products from different stereoisomeric reactants,or which operates on only one of the stereoisomers.Stereospecific reaction is a reaction in which the stereochemistry of the reactant completely determines the stereochemistry of the product without any other option.All stereospecific reactions are stereoselective.When the sterioisomers are enentiomers , the phenomenon is called enantioselctivity.The one of the criteria that a process must meet in the context of click chemistry is that it should be stereospecific but not necessarily enantioselective.
