摘要：
A series of new methyl methyl[1-(substituted phenoxyacetoxy)alkyl]phosphinates was designed and synthesized. Their structures were confirmed by IR, H-1 NMR, P-31 NMR, MS and elemental analysis. The results of bioassay showed that some of the target compounds exhibited excellent herbicidal activities to Triticum aestivum L, Digitaria sanguinalis Scop, Echinochloa crusgalli Beava, Brassica napus L., and Cirsium japonicum DC in pre- and post-emergence treatment at a dosage of 150 g ai/ha. It could be found that the structure of substituent X or Y on a benzene ring had a very important effect on herbicidal activity; compounds 7a, 7b, 7c, and 7i have especially enhanced herbicidal activity and higher selectivity between monocotyledon crops and weeds.

摘要：
A series of potassium methyl 1-(substituted phenoxyacetoxy)alkylphosphonates(9a-9o) was designed and synthesized. The results of preliminary bioassays indicate that most of the title compounds possess excellent pre-emergence and post-emergence herbicidal activities against Brassica napus, Amaranthus mangostanus, Medicago sativa, Echinochloa crusgalli, and Digitaria sanguinalis at a dosage of 1500 g/ha(1 ha=10000 m2). Especially, potassium methyl 1-(2,4-dichlorophenoxyacetoxy)-1-(4-methylphenyl)methylphosphonate(9g) and potassium methyl 1-(2,4-dichlorophenoxyacetoxy)-1-(furan-2-yl)methylphosphonate(9j) show the best herbicidal activity against five tested weeds with more than 85% inhibitory rate in pre-emergence. © 2013 Jilin University, The Editorial Department of Chemical Research in Chinese Universities and Springer-Verlag GmbH.

摘要：
A new, environmentally benign, convenient, and easy method of synthesizing tertiary α-hydroxyphosphonates by the triethylamine-catalyzed hydrophosphonylation of unactivated ketones was developed. In the presence of triethylamine, aromatic or heteroaromatic ketones can react with phosphite to form tertiary α-hydroxyphosphonates under solvent-free and mild conditions. The proposed method was also suitable for functionalized ketones. © 2013 Copyright Taylor and Francis Group, LLC.

摘要：
Pyruvate dehydrogenase complex (PDHc) is the site of action of a new class of herbicides. On the basis of the previous work for O,O′-dimethyl α-(substituted-phenoxyacetoxy)alkylphosphonates (I), further synthetic modifications were made by introducing a fural and a thienyl group to structure I. A series of α-(substituted-phenoxyacetoxy)-α- heterocyclylmethylphosphonate derivatives (II) were synthesized as potential inhibitors of PDHc. The postemergent activity of the title compounds II was evaluated in greenhouse experiments. The in vitro efficacy of II against PDHc was also examined. Compounds II with fural as R<sup>3</sup> and 2,4-dichloro as X and Y showed significant herbicidal activity and effective inhibition against PDHc from plants. O,O′-Dimethyl α-(2,4-dichlorophenoxyacetoxy)- α-(furan-2-yl)methylphosphonate II-17 had higher inhibitory potency against PDHc from Pisum sativum than against PDHc from Oryza sativa in vitro and was most effective against broadleaf weeds at 50 and 300 ai g/ha. II-17 was safe for maize and rice even at the dose of 900-1200 ai g/ha. Field trials at different regions in China showed that II-17 (HWS) could control a broad spectrum of broad-leaved and sedge weeds at the rate of 225-375 ai g/ha for postemergent applications in maize fields. II-17 (HWS) displayed potential utility as a selective herbicide. ©2013 American Chemical Society.

摘要：
A series of 2-methylpropan-2-aminium methyl 1-(substituted phenoxyacetoxy) alkylphosphonates were selectively synthesized by reacting the corresponding dimethyl 1-(substitutedphenoxyacetoxy)alkylphosphonates with an excess of 2-methylpropan-2-amine. All the title compounds were identified by IR, 1H NMR, and 31P NMR, some of them were further analyzed by 19F NMR and 13C NMR. Their herbicidal activity was investigated and the results showed that most of the demethylated aminium salts exhibited notable herbicidal activities against Brassica napus L. and Echinochloa crusgalli.

摘要：
采用孔径10 μm的浮游生物网对A水厂活性炭滤池出水的微型动物进行监测,结果表明泄漏的微型动物优势种类为轮虫、线虫、寡毛类和甲壳类。在活性炭层底部增加厚度为40或50 cm粒径为0.3?0.5 mm的石英砂层,当流速为10?12 m?h~(-1)时,对轮虫、甲壳类和寡毛类等体型较大的微型动物能够截留55%以上,但对线虫截留率较低。建议采用10 μm的微孔滤网过滤氯接触池出水,可使微型动物穿透进入供水管网的风险降低一个数量级,且工作周期达96 h.
