The williamson ether synthesis is an organic reaction, forming an ether from an organohalide and a deprotonated alcohol ()this reaction was developed by alexander williamson in 1850 typically it involves the reaction of an alkoxide ion with a primary alkyl halide via an s n 2 reactionthis reaction is important in the history of organic. We can extend our understanding of the use of this reaction in synthesis by asking how could we make the carboxylic acid we need this combination gives us a two step way to convert an alkyl halide (rbr) to a primary alcohol with the addition of one more carbon to the chain of course.
