METHOD FOR PREPARING LITHIUM COMPLEX SALTS FOR USING IN CHEMICAL CURRENT SOURCE Russian patent published in 2005 - IPC

FIELD: chemistry of organometallic compounds.

SUBSTANCE: invention relates to a method for preparing lithium complexes salts of the general formula (I): wherein each radical R³-R⁶ means hydrogen atom (H) or halogen atom (F, Cl or Br). Method involves mixing a) 3-, 4-, 5-, 6-substituted phenol of the formula (III): wherein R³-R⁶ have above given values with chlorosulfonic acid in acceptable solvent to yield compound of the formula (IV): ; b) intermediate product of the formula (IV) from the stage a) wherein R³-R⁶ have values given above is subjected for interaction with chlorotrimethylsilane to yield compound of the formula (II) given in the invention description and obtained product is filtered off and subjected for differential distillation; c) intermediate product (II) from the stage b) is subjected for interaction with tetramethanolate borate lithium (1-) in acceptable solvent and the end product (I) is isolated from it. Invention provides the development of a simple method for synthesis of lithium complex salts.

EFFECT: improved preparing method.
