FREIDLINA, RAKHIL' KHATSKELEVNA (Organic Chemist) 



R. K. Freidlina was born September 20, 1906. She graduated 

 from Moscow University in 1930 and worked from then until 

 1934 at the Scientific Research Institute of Insectofungicides. 

 In 1935-39 and in 1941-54, she was at the Institute of Organic 

 Chemistry of the U.S.S.R. Academy of Sciences. Freidlina also 

 taught at the Moscow Institute of Fine Chemical Technology in 

 1938-41. In 1945 she became Chief of the Laboratory of the 

 Institute of Organo- Elemental Compounds of the U.S.S.R. Acade- 

 my of Sciences. Since 1958 she has been a Corresponding 

 Member of the U.S.S.R. Academy of Sciences. In 1954 she be- 

 came a member of the Communist Party of the Soviet Union. 



Freidlina has synthesized and investigated the structure and 

 properties of organic compounds of mercury, arsenic, tin, 

 antimony, lead, titanium, silicon, zirconium, boron, fluorine 

 and chlorine. Of theoretical interest are her discoveries of 

 homolytic isomerization of organic compounds in solutions, in- 

 vestigation of adduct of metallic salts to olefin and acetylenes, 

 which led to the establishment of the concept of quasi -complex 

 compounds. Freidlina' s investigations of reactions of telo- 

 merization of olefins and chemical transformations of telomers 

 made possible the development of an industrial method of synthe- 

 sizing intermediate products for production of Soviet synthetic 

 fibers— enanth and pelargon.
