Long, Qingwu,Deng, Xiaoyan,Gao, Yujiao,Xie, Huayong,He, Hongwu,Peng, Hao
, p. 819 - 825 (2013/08/23)
A series of sodium hydrogen 1-(substituted phenoxyacetoxy) alkylphosphonates was designed and synthesized. The test for herbicidal activity indicated that most of the phosphonates (8) possessed excellent postemergence herbicidal activities against broadleaf weeds. Especially, 8f and 8g showed the best herbicidal activity against rape and amaranth with more than 95% inhibitory rate. Supplemental materials are available for this article.

Synthesis and herbicidal activities of lithium or potassium hydrogen 1-(substituted phenoxyacetoxy)alkylphosphonates
Peng, Hao,Long, Qingwu,Deng, Xiaoyan,He, Hongwu
, p. 1868 - 1874 (2013/11/06)
A series of lithium or potassium hydrogen 1-(substituted phenoxyacetoxy)alkylphosphonates were designed and synthesized. All the title compounds were identified by IR, 1H NMR, and 31P NMR, some of them were further analyzed by MS and elemental analyses. The test for herbicidal activity indicated that most of the phosphonates (8) possessed excellent postemergence herbicidal activities against broadleaf weeds.

Simple and improved preparation of α-oxophosphonate monolithium salts
Wang, Tao,Hong, Wu He
, p. 2081 - 2089 (2007/10/03)
Some α-OxoPhosphonate monolithium salts were synthesized by a facile one-step procedure. In this way, α-(2,4-dichlorophenoxyacetoxy)alkyl phosphonic acid dimethyl esters 5 can be transformed into the corresponding phosophonate monolithium salts 6 without influence on the carboxylic ester group under mild conditions.
An efficient synthesis of α-(2,4-dichlorophenoxyacetoxy)aryl methyl phosphonate monosodium salts
Wang, Tao,He, Hong Wu
, p. 1415 - 1423 (2007/10/03)
A series of α-(2,4-dichlorophenoxyacetoxy)aryl methyl phosphonate monosodium salts 6 were synthesized by the reaction of the intermediate 5 with sodium iodide under moderate condition. This method was applied to the synthesis of novel phosphonate derivati
Synthesis and dealkylation of 1 -(dichloro-phenoxyacetoxy) alkyl phosphonates
He, Hongwu,Liu, Xufeng,Hu, Liming,Wang, Siquan,Liu, Zhaojie
, p. 633 - 636 (2007/10/03)
Using the silylation procedure with chlorotrimethylsilane/sodium iodide followed by alcoholysis, 1-(dichlorophenoxy acetoxy)alkyl phosphonic acid dimethyl esters can be transformed into the parent phosphonic acids without influence on carboxylate ester group.
