Question
Chapter FRP, Problem 23P
Interpretation Introduction
Interpretation:
The mechanistic rationalizations of the different products on the dehalogenation of meso and enantiomeric 2,3-dibromobutane are to be demonstrated.
Concept introduction:
Meso compounds have multiple stereocenters and also are superimposable on their mirror image.
Enantiomers are the chiral molecules that are mirror images of one another.
The reagent, potassium iodide, is a water-soluble inorganic salt.

- Both cis- and trans-2-methylcyclohexanol undergo dehydration in warm sulfuric acid to give 1-methylcyclohexene as the major alkene product. These alcohols can also be converted to alkenes by tosylation using TsCl and pyridine, followed by elimination using KOC(CH3)3 as a strong base. Under these basic conditions, the tosylate of cis-2-methylcyclohexanoleliminates to give mostly 1-methylcyclohexene, but the tosylate of trans-2-methylcyclohexanol eliminates to give only 3-methylcyclohexene.
