Johannes Wislicenus (German pronunciation: [joˈhanəs vɪsliˈt͜seːnʊs]; 24 June 1835 – 5 December 1902) was a German chemist, most famous for his work in early stereochemistry.

Biography

The son of the radical Protestant theologian

University of Leipzig, where he died on 6 December 1902.^[2]

Research

By the late 1860s,^[

J. H. van't Hoff's theory of the tetrahedral carbon atom, believing that it, together with the supposition that there are "specially directed forces, the affinity-energies",^[2] which determine the relative position of atoms in the molecule, afforded a method by which the spatial arrangement of atoms in particular cases may be ascertained by experiment. While at Würzburg, Wislicenus developed the use of ethyl aceto acetate in organic synthesis.^[2] However, he was also active in inorganic chemistry, finding a reaction for the production of sodium azide. He was the first to prepare cyclopentane in 1893^[4]

Awards

In 1898 Wislicenus was awarded the Davy Medal by the Royal Society of London.^[2]

Wislicenus prepared cyclopentane from cyclopentanone ("Ketopentamethen"), which is prepared by heating calcium adipate.
