摘要:以亚磷酸二乙酯和糠醛为原料,三乙胺做催化剂,经加成反应制得α-羟基膦酸酯,再经酯化反应制得8个含呋喃环新型膦酸酯衍生物II,采用^(1)H NMR、^(13)C NMR、^(31)P NMR、MS、IR以及元素分析对其进行了结构表征,并评价了除草活性和杀草谱。大部分目标化合物在150 g ai/ha剂量下对苘麻(Abutilon theophrasti)、反枝苋(Amaranthus retroflexus)和鳢肠(Eclipta prostrata)具有70~100%抑制活性。扩大杀草谱测试结果表明,化合物II-1和II-2在150 g ai/ha剂量下对部分杂草具有显著的抑制活性,与对照药剂草甘膦相当。
Using diethyl phosphite and furfural as raw materials,triethylamine as catalyst,α-hydroxyphosphonate was produced by addition reaction.And then eight novel phosphonate derivatives containing furan II were synthesized by the reaction ofα-hydroxyphosphonate with substituted phenoxybutanoyl chloride.The structures of the target compounds were characterized by ^(1)H NMR,^(13)C NMR,^(31)P NMR,MS,IR and elemental analysis.Most of compounds II showed 70~100%inhibition against Abutilon theophrasti,Amaranthus retroflexus and Eclipta prostrata at 150 g ai/ha.A broad-spectrum test confirmed that compounds II-1 and II-2 were comparable with glyphosate against some of the tested weeds at 150 g ai/ha rate.
