Abstract:
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 C1-C4 straight or branched alkyl X and Y are independently selected from the group consisting of hydrogen, fluorine, chlorine, bromine, iodine, R1O— and R1S— wherein R1 is C1-C4 straight or branched alkyl chain.
