摘要：
The present invention relates to a process for the cyclopropanation with ethylene carbonate or ethylene sulfate of a compound of formula (II):
wherein G is -CN or -COOR in which R is a C 1 -C 4 straight or branched alkyl X and Y are independently selected from the group consisting of hydrogen, fluorine, chlorine, bromine, iodine, R 1 O- and R 1 S- wherein R 1 is C1-C4 straight or branched alkyl chain.
