ORGANIC PHOSPHORUS COMPOUNDS 93. PREPARATION, PROPERTIES AND HERBICIDAL ACTIVITY OF 2-SUBSTITUTED 5-PHENOXY- AND 5-PYRIDYLOXY-PHENYLAMINOALKYLPHOSPHONIC- AND -PHOSPHINIC ACID - AS WELL AS - PHOSPHINE OXIDE DERIVATIVES

Interaction of 4-phenoxy and 4-pyridyloxy substituted 1,2-dinitrobenzenes and aminoalkylphosphonates, -phosphinates, and -phosphine oxides produces mainly 5-phenoxy- and 5-pyridyloxy substituted 2-nitrophenylaminoalkylphosphonates, -phosphinates and -phosphine oxides (Table I to IV and Figure 1 to 5), some of which show high herbicidal and plant growth regulating activity.The herbicidal activity increases from pyridyloxy-phenylaminoalkylphosphonates to phenoxy-phenylaminoalkyl-phosphonates, -phosphinates, -phosphine oxides.Of all the compounds tested the phosphine oxide 4a was at all concentrations the most active compound.

Herbicidal N-2-(nitro-5-phenoxy-phenyl)-aminoalkylphosphonic acid and esters

The present invention relates to (2-nitro-5-aryloxyphenylamino)alkylphosphonic, -alkylphosphinic and -alkylphosphonous acid derivatives of the general formula I STR1 wherein X is halogen, CF3, NO2, CN, CONH2 or CSNH2
