Williamson, Alexander William

Alexander William Williamson (1824-1904) was born in London of Scottish parents. In 1849, he became Professor of Chemistry at University Colleye, London. [Pg.68]

Parallel to and largely independent of the work discussed so far, a second line of research led to important conclusions that were of use in the development of the valence concept. In the third paper, dated 1851, Alexander William Williamson (1824 1904) suggested that an atomic grouping (CO) holds together two parts of a molecule which would otherwise fall apart. This conception can be traced back to Liebig s researches on polybasic acids, which in... [Pg.24]

Alexander William Williamson (1824-1904) was bom in London to Scottish parents. Ay a child, he lost an arm and the use of an eye. He was midway through his medical education when he changed his mind and decided to study chemistry. He received a Ph.D. from the University of Geissen in 1846. In 1849, he became a professor of chemistry at University College, London. [Pg.425]

R Cl + RO-Na+ R OR + NaCl The product ether is termed mixed if the alkyl groups R and R are different. This synthesis can produce both simple and mixed ethers. The synthesis is named for the British chemist Alexander William Williamson (1824-1904). [Pg.290]

Between 1850 and 1852, the English chemist Alexander William Williamson (1824-1904) showed that the family of organic compounds called ethers... [Pg.108]

Alcoholates (alkoxides), which were already mentioned in the discussion on the reactions of alcohols with metals, behave as strong bases and are good nucleophiles. In the middle of nineteenth century Alexander William Williamson succeeded in preparing ethers in the reactions of alkoxides with primary alkyl halides. Later it was demonsttated that these reactions follow the Sn2 mechanism. [Pg.76]

At the same time Alexander William Williamson (1824-1904) was trying to prepare higher alcohols by substituting the hydrogen in ethanol by an alkyl radical. When he reacted ethanol with potassium ethoxide, he found that instead of another alcohol he obtained diethyl ether. This synthesis meant that ethanol could not be the hydrate of ether as Liebig had proposed, and Williamson suggested the existence of a water type,... [Pg.116]

Alexander William Williamson was an English chemist who lived between 1824 and 1904. His method is especially useful for synthesis of unsymmetrical ethers. [Pg.523]

Robert William Atkinson was bom in Newcastle in England. After studies at the University College, London, under Alexander Williamson and the Royal School of Mines under Edward Frankland between 1867 and 1872, he became an assistant of Alexander Williamson, professor of chemistry at University College, London. Atkinson came to Japan on September 9th, 1874, and stayed until 1881. After his return, he lived in Cardiff, Wales.
