具有生物活性的有机磷化合物的研究V，α－［（取代）芳氧基乙酰氧基］烷基膦酸酯的合成和性质

Study on Biologically Active Organophosphorus Compounds V. Syntheses and Properties of α-(Substituted Phenoxy-acetoxy)Alkyl Phosphonates

过取代苯氧乙酰氯和α－羟基烷基胰酸酯的缩合反应合成了８种标题化合物，用元素分析，红外，核磁及质谱作了表征，测定了它们的除草活性和植物生长调节活性。

Eight title compounds were synthesized by condensation of substituted phenoxyacetyl chlorides and ahydroxy alkyl phosphonates.Their structures were characterized byelemental analysis, IR,￣1H NMR,￣(31)P NMR measurements and their herbicidal activities andplant growth regularing activities were tested.Some of them( I_g,I_c,I_d,I_h,and I_i )werefound to exhibit a marked activity.
