Problem 73SP
Pure (S)-2-bromo-2-fluorobutane reacts with methoxide ion in methanol to give a mixture of (S)-2-fluoro-2-methoxybutane and three fluoroalkenes.
(a) Use mechanisms to show which three fluoroalkenes are formed.
(b) Propose a mechanism to show how (S)-2-bromo-2-fluorobutane reacts to give (S)-2-fluoro-2 methoxybutane. Has this reaction gone with retention or inversion of configuration?
a).
2-Bromo-2-Fluorobutane 2-fluoro-2-methoxybutane
Three fluoroalkanes are as under
b). Inversion- it is a process in which the configuration of an atom is changed.
Like R changes to S or vice versa, and
Cis into trans and vice versa.
