2,4-diamino-1,3,5-triazines, processes for their preparation and their use as herbicides and plant growth regulators

摘要

Compounds of the formula (I) and their saltsin whichR1 is optionally substituted (C1-C6)alkyl or optionally substituted phenyl,A is an optionally substituted hydrocarbon diradical andR2, R3, R4, R5, X and n are as defined in claim 1, are suitable as herbicides and plant growth regulators. The compounds (I) can be prepared according to processes as claimed in claim 6 by means of intermediates which are novel in some cases, e.g. of the formula (IV) as claimed in claim 10.
