Cornelius Gerhard Kreiter

from Wikipedia, the free encyclopedia

Cornelius Gerhard Kreiter (* 1937 in Vișeu de Sus , Romania ) is a German chemist.

Kreiter studied chemistry at the University of Munich from 1958 . He received his diploma in 1961 and in 1964 with a thesis on NMR Spectroscopy of Organometallic Compounds with Ernst Otto Fischer on the topic "PMR spectroscopy of metal-carbon bonds" doctorate . Kreiter was from 1964 to 1965 as a postdoc with Herbert D. Kaesz (1933–2012) University of California, Los Angeles in the USA. In 1971 he completed his habilitation with HP Fritz (1930–2007) as a mentor at the Technical University of Munich and was then a private lecturer there. In 1976 he was appointed full professor at the second newly created chair for inorganic chemistry at the University of Kaiserslautern . Kreiter retired in the winter semester 2002/2003. He was then actively involved in the development and promotion of chemical university education in the Rhineland Palatinate partner country Rwanda .

Kreiter was visiting professor at Montpellier University (1985), New York University (1991), Middle East Technical University in Ankara (1993) and Catania University (1999).

Kreiter mainly dealt with the reactivity and structure of carbonyl complexes of the metals Cr, Mo, W, Mn, Re, Fe. In his work he mainly used NMR spectroscopic methods to elucidate the bonding relationships and the dynamic stereochemistry of the compounds under investigation. Kreiter discovered a number of metal-directed formal cycloadditions such as B. [6 + 4], [5 + 4] ,, [5 + 2] [5 + 2] homo [5 + 2], which are suitable for the construction of medium-sized ring systems and carbocycles.

His student Saim Özkar became Professor of Inorganic Chemistry at the Middle East Technical University in Ankara.
