Question

What structure goes through halogenation to produce (2R,3S)-2,3-dichlorobutane?

Answer 1

The structure that goes through halogenation to produce (2R,3S)-2,3-dichlorobutane is (R)-2-butanol.

The reaction involves the substitution of a hydrogen atom on the second carbon (C2) of (R)-2-butanol with a chlorine atom to form (2R,3S)-2,3-dichlorobutane.

Here is the reaction:

(R)-2-butanol + Cl2 → (2R,3S)-2,3-dichlorobutane

Answer 2

the starting material has to be an alkene

Answer 3

I apologize for the incorrect response. For the formation of (2R,3S)-2,3-dichlorobutane, the starting material should be an alkene.

The alkene that can undergo halogenation to produce (2R,3S)-2,3-dichlorobutane is (E)-2-butene.

Here is the reaction:

(E)-2-butene + Cl2 → (2R,3S)-2,3-dichlorobutane
