Abstract
The halophenoxy-alkoxy phosphonates and corresponding thiophosphonates of the present invention are represented by the general formula: ##STR1## wherein R is alkylene having from 1 to 4 carbon atoms; Y is O or S; X is --OH, halo, ##STR2## ,--ORSROH, or --OH.N4R"'(ROH); Z is --OH, halo, ##STR3## when X is --OH.N4R"'(ROH), then Z can also be --OH.N4R"'(ROH); R' is H or alkyl having from 1 to 4 carbon atoms; R" is C.sub.1-4 alkyl sulfonic acid or a salt thereof, such as the halide or alkali metal salt; R"' is H or --ROH; and m is an integer from 1 to 5 and wherein at least one of X and Z is other than --OH. These compounds are particularly useful as pre-emergent herbicides and lubricants or lubricant additives.
