When did Alexander Williamson invent the Williamson ether synthesis?
RXNO:0000090. The Williamson ether synthesis is an organic reaction, forming an ether from an organohalide and a deprotonated alcohol (alkoxide). 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 N2 reaction.
How is phenacetin made by the Schotten-Baumann reaction?
Phenacetin can also be made by the Schotten-Baumann reaction which is an organic reaction used to convert an acyl halide or anhydride to an amide if reacted with an amine and base. In this reaction there is use of added base to drive the equilibrium in the formation of amides from amines and acid chlorides.
When does the Williamson reaction compete with alkylation?
When the nucleophile is an aryloxide ion, the Williamson reaction can also compete with alkylation on the ring since the aryloxide is an ambident nucleophile . ^ Burgstahler, Albert W.; Worden, Leonard R. (1966).
Who was the first person to synthesise phenacetin?
The first synthesis was reported in 1878 by Harmon Northrop Morse. Phenacetin may be synthesized as an example of the Williamson ether synthesis: ethyl iodide, paracetamol, and anhydrous potassium carbonate are refluxed in 2-butanone to give the crude product, which is recrystallized from water.
