Page/Page column 12; 14, (2008/06/13)
The present invention refers to a process for preparing a compound of the formula (I) wherein R denotes an organic radical which, together with the two carbon atoms to which it is bonded, forms a carbocyclic or heterocyclic ring; R1, R2, R3 and X, independently, denote hydrogen, halogen, nitro, cyano or an organic radical; or R1 and R2 or R2 and R3, together with the carbon atoms to which they are bonded, form a ring; which comprises exposing a compound of the formula (II) wherein R1, R2, R3 and X are defined as given above and Y and Z, independently, have one of the meanings of X; to an energy source in the presence of a catalyst system.
