Abstract: A process for preparing benzophenones of the formula I, where X may be chlorine, hydroxyl, methoxy or C 1 -C 6 -alkylcarbonyloxy, and Y may be chlorine or bromine, by reacting an acid chloride of the formula II where X and Y are as defined above with 3,4,5-trimethoxytoluene, which comprises carrying out the reaction in the presence of a) an aromatic hydrocarbon as a diluent and b) from 0.01 to 0.2 mol % of an iron catalyst, based on the acid chloride, c) at a temperature between 60° C. and the boiling point of the particular diluent.

Abstract: A process is disclosed for producing isomer mixtures from O- phenoxyalkylhydroxyl amines Ia: H2N-O-CH2-CH(R1)-O-Ar and Ib: H2N-O-CH(R1)-C H2- O-Ar (wherein R1 represents alkyl, Ar where appropriate a substituted phenyl ) and the corresponding salt mixtures. This process involves the following steps: (a) an isomer mixture of O-(2-hydroxyethyl)-oximes (IIa) and (IIb) (i n which R2 is an alkyl and R3 is an alkyl or alkoxy, or R2 and R3 together wit h the common C atom form a 5-7 member ring) is converted by reaction with a sulphonyl halogenide of formula (III): Hal-SO2-R4 (wherein R4 represents an organic group and Hal is a halogen) in the presence of a base to form the corresponding sulphonate mixture of (IVa) and (IVb); (b) this sulphonate mixture is reacted in the presence of a base with a phenol of formula (V): H O- Ar to produce a mixture of O-phenoxyalkyloximes of general formulae (VIa) an d (VIb); (c) the mixture is hydrolysed in the presence of an acid and, if required, (d) the O-phenoxyalkylhydroxyl amines (Ia) and (Ib) are released from the resulting salts using a mineral base. The O-phenoxyalkylhydroxyl amines (Ia/Ib) and their precursors (VIa/VIb) are important intermediate products for plant protective agents and drugs.
