METHOD OF PRODUCING TERTIARY CYCLIC ALCOHOLS OF 2,2'-BITHIOPHENE SERIES Russian patent published in 2013 - IPC C07C33/12 C07C33/14 C07C33/16 C07F3/02

Abstract RU 2495018 C2

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing tertiary cyclic alcohols of the 2,2'-bithiophene series by reacting 5-bromo-2,2'-bithiophene or 5-iodo-2,2'-bithiophene and magnesium in absolute diethyl ether with a cycloalkane in molar ratio of 1:1:1 (for adamantanol 1:1:0.8), at temperature of 35-36°C for one hour.

EFFECT: simple process due to use of readily available reactants, use of an acceptable molar ratio of reactants, shorter overall duration of the reaction, low cost of production due to a simple reactor scheme.
