Herbicidal diphenyl ethers

Abstract

Diphenyl ethers of the formula ##STR1## wherein R.sup.1 is hydrogen or halogen, R.sup.2 is hydrogen, halogen, or cyano, R is ##STR2## wherein R.sup.3 is hydrogen, halogen, nitro, alkyl, or alkoxy, R.sup.4 is a divalent alkylene radical, and R.sup.5 is cyano or -COR.sup.6, wherein R.sup.6 is alkoxy, hydroxy or salt thereof, allyloxy, alkoxyalkoxy, amino, alkyl or dialkyl amino, aminoalkoxy, or alkyl or dialkylaminoalkoxy, And diphenyl sulfides, sulfoxides, and sulfones of the formula ##STR3## wherein R.sup.8 is hydrogen, halogen, cyano, nitro, alkyl, alkoxy, or trifluoromethyl, R.sup.2 is hydrogen, halogen or cyano, X is sulfur, sulfinyl, or sulfonyl, and R is as defined above, And compositions containing these compounds exhibit herbicidal activity.
