WebOct 24, 2014 · The Williamson Ether synthesis is an S N 2 reaction. Remember that since the S N 2 reaction proceeds through a single step where the nucleophile performs a “backside attack” on the alkyl halide, the “big barrier” for the S N 2 reaction is steric hindrance. The rate of the S N 2 reaction was highest for methyl halides, then primary, … WebOct 30, 2014 · The Williamson Ether synthesis proceeds through an S N 2 mechanism. When planning the synthesis of an ether through the Williamson, remember that S N 2 reactions work well for primary and methyl alkyl halides and fail for tertiary alkyl halides. Also, S N 2 reactions do not work at all with alkenyl or aryl halides.
