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.
