摘要:
The invention relates to novel intermediates for the preparation of a certain group of novel phenylsulfonylurea herbicides, which herbicides are particularly advantageous for use in crop protection. The novel intermediate compounds are of the formula II ##STR1## and of the formula VI, ##STR2## as defined in the specification and claims. The intermediate compounds may be used to prepare herbicidal and plant growth regulating compounds of the formula I or salts thereof: ##STR3## as defined in the specification. The herbicides so obtained are particularly suitable for selectively controlling weeds.

To prepare them, a cyclohexanedione can be reacted a) with a 4-oxy-substituted benzoyl chloride and the resulting enol ether can be rearranged, or b) with a benzoyl cyanide. The benzoyl chloride or benzoyl cyanide required can be obtained from correspondingly substituted toluenes via the carboxylic acid.
