Process for the preparation of O-phenoxyalkyloximes and O-phenoxyalkylhydroxylamines |
| abstract |
A process is disclosed for producing isomer mixtures from O-phenoxyalkylhydroxyl amines Ia: H2N-O-CH2-CH(R<1>)-O-Ar and Ib: H2N-O-CH(R<1>)-CH2-O-Ar (wherein R<1> 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) (in which R<2> is an alkyl and R<3> is an alkyl or alkoxy, or R<2> and R<3> together with the common C atom form a 5-7 member ring) is converted by reaction with a sulphonyl halogenide of formula (III): Hal-SO2-R<4> (wherein R<4> 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): HO-Ar to produce a mixture of O-phenoxyalkyloximes of general formulae (VIa) and (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. |
