| titleOfInvention | Process for the preparation of cyclopropane derivatives, intermediates in the synthesis of pyrethroid insecticides |
| abstract | Compounds of formula: <IMAGE> 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: <IMAGE> 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: <IMAGE> 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. |
