三丁基锡烃氧(硫)乙酸盐的合成和除草活性测定

Synthesis of Tributyltin Alkyloxy- and Aryloxy(thio-)acetates and Their Herbicidal Activity

本文报道了13种三丁基锡烃氧(硫)乙酸盐的合成及其除草活性的初筛和复筛结果,讨论了化合物的IR和NMR谱,农药活性的测定结果表明,该类化合物的除草活性优于或接近除草剂2,4-D(2,4-二氟苯氧乙酸)。

Thirteen tributyltin alkyloxy- and aryloxy(thio)acetates were synthesized by the reaction of TBTO and relative acids. All compounds were analyzed for 1R spectra, 1H, I3C and 119Sn NMR. The results show that they may be five-coordinated organotin compounds with bridging carboxyl group and tin intermolecular. The pesticidal activity of some compounds have been determined and they display a good herbicidal activity.
