Abstract

Procedure for the preparation of phenylbenzyl ketone derivatives of the general formula I **(See formula)** (wherein R1 means a hydrogen atom or an alcohol group with 1 to 6 carbon atoms, and R2 means a hydrogen atom or an alcohol group with 1 to 20 carbon atoms unsubstituted or substituted by an alkoxy group with 1 to 6 carbon atoms, an OH group, a phenyl group or a halogen-phenyl group, provided that in the event that R2 means hydrogen, R1 cannot represent methyl or ethyl, and in the event that R2 means methyl, R1 cannot represent hydrogen, methyl or ethyl, characterized in that a compound of the general formula III is reacted **(See formula)** (where R1 and R2 have the above meanings, provided that at least one of these symbols is not hydrogen, or one of the symbols means hydrogen or an eventually substituted alcoholic group, as indicated above, and the other symbol means a phenylacetyl group), with benzyl cyanide in an aprotic solvent in the presence of an acid catalyst, or said compound is subjected to a Fries rearrangement in the presence of a Lewis acid catalyst or under illumination.
