Abstract EN
The conformational analysis of five β-chloro- and β-bromo-alkoxides had been done.
The minima and the conformational transition states were determined.
The anti conformer was found to be the most stable one.
Its percentage is more than 99.
α-Methylation increases the nuclophilicity of oxygen .Consequently, it enhances the rate of the ring closure.
In contrast to β-methylation which retards the rate of the ring closure.
This observation could be attributed to the reactivity of alkyl halides in SN2 reactions.
The rearrangements of g and g- conformers to carbonyl compounds are not feasible.
Therefore, the main rearrangement that takes place in β-haloalkoxides is the formation of epoxides.
