Background

Alex & # 769; PDR Micha & # 769; ylovich Per & # 769; ytsev (20 of June (2 July) in 1841 - 19 August (1 September), 1910) - Russian organic chemist, corresponding member of the St. Petersburg Academy of Sciences (1885) .Uchenik A . AM Butlerov. At the end of the Kazan University, he worked (1862-65) in the laboratories of A. Kolbe and A. Wurtz Sh. In 1870 he defended his doctoral thesis "The new method of converting fatty acids into their corresponding alcohols" and was approved by the extraordinary, and in 1871 - an ordinary professor of Kazan University.

Zaitseva studies contributed to the development and strengthening of the chemical structure of Butlerov theory. Since 1870 Zaitsev conducted research on saturated alcohols, moreover developed a general method for the synthesis of fatty acid chlorides by reduction with sodium amalgam. In particular, he received a normal primary butanol, whose existence was predicted by the theory of the structure. In 1873 Zaitsev synthesized diethylcarbinol action of zinc on a mixture of ethyl iodide and ethyl formate. This work laid the foundation for studies of French chemists F. Barbier, Grignard F. et al. (See. As the Grignard reaction). In 1885, Zaitsev proposed a new method for the synthesis of tertiary alcohols limit the action of zinc on a mixture of alkyl halide and ketone. In 1875-1907 Zaitsev synthesized a number of unsaturated alcohols. Designed by Zaitsev and his students synthesis methods using halogen-organozinc compounds yielded a large number of saturated and unsaturated alcohols and their derivatives. Together with students Zaitsev synthesized a number of unsaturated hydrocarbons (butylene, diallyl and OE). Of particular importance are the theoretical research on the procedure for joining Zaitseva elements hydrogen halides (HX) to unsaturated hydrocarbons and elimination of HX from alkyl halides (Zaitsev`s rule). A number of works by Zaitsev and his students devoted to polyatomic alcohols and oxides, obtaining unsaturated acids, hydroxy acids and lactones - a class of organic compounds, open Zaitsev in 1873. Zaytsev trained a large school of chemists (EE Wagner, AE Arbuzov, SN . Reformed, Reformed AN, II Kanonnikov et al.).
