Alexander Williamson. Williamson is credited for his research on the formation of unsymmetrical ethers by the interaction of an alkoxide with a haloalkane, known as the Williamson ether synthesis. He regarded ethers and alcohols as substances analogous to and built up on the same type as water, and he further introduced the water-type as a ...
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. [ 2 ] Typically it involves the reaction of an alkoxide ion with a primary alkyl halide via an S N 2 reaction .
Alexander Williamson may refer to: Alexander William Williamson (1824–1904), chemist who discovered the Williamson ether synthesis reaction Alexander Williamson (missionary) (1829–1890), Scottish Protestant missionary to China with the London Missionary Society
The industrial synthesis entails the reaction of hydrogen chloride with a solution of sulfur trioxide in sulfuric acid: [7] HCl + SO 3 → ClSO 3 H It can also be prepared by the method originally used by acid's discoverer Alexander William Williamson in 1854, [ 4 ] namely chlorination of sulfuric acid, written here for pedagogical purposes as ...
Alexander William Williamson (1824–1904), English chemist, famous for Williamson ether synthesis; Thomas Willson (1860–1915), Canadian chemist, discovered an economically efficient process for creating calcium carbide; Richard Willstätter (1872–1942), German chemist, 1915 Nobel Prize in Chemistry
The synthesis by De Clermont and Moschnin was based on the earlier work by Alexander Williamson (who is well known for the Williamson ether synthesis). [6] Their synthesis made use of ethyl iodide and silver salts to form esters in combination with pyrophosphate. [7] Ag 4 P 2 O 7 + 4EtI → [(EtO) 2 P(O)] 2 O + 4AgI
When the metal atom is not desired in the final product, a disadvantage of templated synthesis is the difficulty in removing the templating metal from the macrocyclic ligand. 18-Crown-6 can be synthesized by the Williamson ether synthesis using potassium ion as the template cation.
18-Crown-6 can be synthesized by the Williamson ether synthesis using potassium ion as the template cation. Structure of nickel-aquo nitrate complex of the ligand derived from the templated trimerization of 2-aminobenzaldehyde. [5] The phosphorus analogue of an aza crown can be prepared by a template reaction. [6]
