摘要:Compounds of formula: wherein both groups X are chlorine, bromine or trifluoromethyl, or one X is chlorine or bromine and the other is trifluoromethyl, and Y is -CN or -COOR in which R is an alkyl group, are obtained by (A) reacting a compound of the formula: wherein X1 is chlorine or bromine, with a compound of the formula: X2C=CH-CH=C(CH3)2 in the presence of metallic copper or at least one copper salt and a base, or (B) reacting a compound of the formula: Y-CH2-CN with a compound of the formula: X2C=CH-CH=C(CH3)2 and chlorine or bromine, in the presence of at least one reducible copper salt and a base, or (C) reacting a compound of formula: X-CH2-CN with a compound of the formula: wherein X1 is chlorine or bromine, in the presence of at least one copper salt. The compounds are intermediates in the synthesis of pyrethroid insecticides.

摘要:A method of forming an electrolyte solution involves combining ammonium tetrafluoroborate and spiro-bi-pyrrolidinium bromide in a liquid solvent to form spiro-bi-pyrrolidinium tetrafluoroborate and an ammonium halide. The ammonium halide precipitate is removed from the solvent to form an electrolyte solution. The reactants can be added step-wise to the solvent, and the method can include using a stoichiometric excess of the ammonium tetrafluoroborate to form a substantially halide ion-free electrolyte solution.

摘要:A method of forming an electrolyte solution involves combining ammonium tetrafluoroborate and a quaternary ammonium halide in a liquid solvent to form a quaternary ammonium tetrafluoroborate and an ammonium halide. The ammonium halide precipitate is removed from the solvent to form an electrolyte solution. The reactants can be added step-wise to the solvent, and the method can include using a stoichiometric excess of the ammonium tetrafluoroborate to form a substantially halide ion-free electrolyte solution.
