Xenofont Alexandrovich Kocheshkov

Xenofont Alexandrovich Kotscheschkow ( Russian Ксенофонт Александрович Кочешков , English transcription Ksenofont Aleksandrovich Kocheshkov, scientific. Transliteration Ksenofont Aleksandrovič Kočeškov * thirtieth November 1894 in Moscow ; † 15. January 1978 ) was a Soviet chemist ( Organic Chemistry ).

Kocheschkow studied at the Lomonossow University with the degree in 1921 and was there a student of Nikolai Dmitrijewitsch Selinski . In 1935, after his habilitation (Russian doctorate), he became a professor in the organic chemistry department at Lomonossow University. In the mid-1930s, he and Alexander Nikolajewitsch Nesmejanow created the lecture series on element-organic compounds. In 1944 he became head of the laboratory for element-organic compounds at Lomonossow University and from 1945 of the laboratory for organometallic chemistry at the physicochemical research institute L. Ja. Karpov (NIFKHI).

He dealt with organometallic chemistry and here an important synthetic method is named after him ( Kotscheschkow rearrangement ). In 1949 his monograph on synthetic methods of organic compounds with alkali metals (lithium, sodium, potassium, rubidium, cesium) was published, written with TW Talalajewa. In 1942, both of them succeeded in synthesizing organic tin compounds by reacting tin amalgam with organic lithium compounds. Their process had a high yield, although Erich Krause previously considered this route to be impassable due to geometric obstacles. He found new synthesis methods for amines with the help of organometallic compounds.

He was a member of the Soviet Academy of Sciences (corresponding in 1946 and full member in 1968), became a Hero of Socialist Labor in 1974 and received the Lenin Prize twice (1954, 1974), the Stalin Prize in 1948 (2nd class) and the State Prize of the USSR in 1967.

He was editor of the Elements of Organoelement Chemistry .
