Karl Brunner (chemist)

from Wikipedia, the free encyclopedia

Karl Brunner (born April 1, 1855 in Linz , † October 21, 1935 in Innsbruck) was an Austrian chemist.

Life

Karl Brunner was born in 1855 as the son of a Lieutenancy Councilor. From 1873 he studied at the University of Innsbruck , where he later received his doctorate . In the years from 1885 to 1902 he taught at a secondary school and was chief inspector at the food inspection institute in Prague . He then went back to the University of Innsbruck where he retired in 1926 . His research area was initially polyhydric phenols . In 1902 he was appointed to succeed Karl Senhofer (born September 29, 1841 in Griesbruck, † October 17, 1904 in Innsbruck) at the University of Innsbruck, where he retired in 1926. He continued his work at the institute until shortly before his death.

In this area he developed the Senhofer-Brunner method with which carboxy groups can easily be substituted on the phenols. He later devoted himself to the field of indoles . Analogous to the indole ring closure by Emil Fischer (1883), he developed the oxindole ring closure as a process for oxindole synthesis. In 1914 he expanded the triazole synthesis developed by Alfred Einhorn (published in 1905) to synthesize 1,2,4-triazoles from hydrazines and diacylamines.

He is not to be confused with the Swiss chemist Karl Emanuel Brunner .
