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
摘要 通过相应的1-(取代苯氧基乙酰氧基)烷基膦酸二甲酯与过量的2-甲基丙-2-胺反应,选择性地合成了一系列2-甲基丙-2-氨基甲基1-(取代苯氧基乙酰氧基)烷基膦酸酯。所有标题化合物均经IR、1H NMR和31P NMR鉴定,其中部分化合物经19F NMR和13C NMR进一步分析。研究了它们的除草活性,结果表明,大多数去甲基化的胺盐对欧洲油菜和稗子表现出显着的除草活性。补充材料可用于本文。访问出版商在线版的磷、硫和硅及相关元素,获取以下免费补充文件:附加文本、图表和表格。图形概要
