A series of 2-methylpropan-2-aminium O-methyl 1-(substituted phenoxyacetoxy)alkylphosphonates (5a-5o) was selectively synthesized by reacting the corresponding O,O-dimethyl 1-(substituted phenoxyacetoxy)-alkylphosphonates with an excess of 2-methylpropan-2-amine. The results of preliminary bioassays show that the title compounds exhibit moderate to good herbicidal activities against Brassica napus and Echinochloa crusgalli. Furthermore, compounds 5a-5j, which show much higher activities than compounds 5k-5o, were selected to further evaluate th...
