Rolf Huisgen (born June 13, 1920 in Gerolstein , Eifel ; † March 26, 2020 in Munich ) was a German chemist . He was best known for his work on 1,3-dipolar cycloaddition reactions.

life and work

After graduating from the Staatliche Reginoschule in Prüm , Huisgen began studying chemistry at the University of Bonn and then switched to the Ludwig Maximilians University of Munich (LMU Munich). As a student of Nobel Prize winner Heinrich Otto Wieland , he was in 1943 at the University of Munich with the work contributions to the knowledge of the Vomicins doctorate . In 1947 he received his habilitation and became a private lecturer . In 1949 he was appointed associate professor for organic chemistry at the Eberhard Karls University in Tübingen . In 1952 he received a call back to the LMU Munich as a full professor and head of the Institute for Organic Chemistry. Since 1988 he has been emeritus . Rolf Huisgen was a widely cited author of around 590 scientific publications in international journals. Its importance is also shown in the fact that in Germany alone 16 of his students became full professors.

The main area of ​​his research was physical organic chemistry . The focus of his interest was in particular the reaction class of [3 + 2] cycloadditions or 1,3-dipolar cycloadditions , which are often named after him (“ click chemistry ”). The Diels-Alder reaction was known as a typical cycloaddition , in which an alkene reacts with a four-atom diene to produce the six-membered rings. If alkenes are allowed to react with triatomic carbon compounds that act as dipoles with a positive charge at one end and a negative charge at the other end, five-membered rings are often formed, and Huisgen found that there is a reaction mechanism of its own without intermediates or free radicals. Huisgen published these findings in 1963. The dipolar cycloaddition (1,3-dipolar cycloaddition of alkenes or alkynes with 1,3-dipolar molecules such as azides, nitrile oxides or diazoalkanes) is sometimes named after him. The Huisgen pyrrole synthesis is also named after him.

In 2019 the media group Clarivate counted him among their favorites for a Nobel Prize ( Clarivate Citation Laureates ).

Private

Huisgen married his colleague Trudl Schneiderhahn in 1946. The marriage was between Birge Huisgen-Zimmermann , born in 1946 , mathematician and professor at the University of California, Santa Barbara , and Helga Huisgen, born in 1949, interpreter and translator of American literature.
