本文合成了一系列芳氧乙酰氧(亚甲)基硅烷类化合物,大部分为文献尚未报道的新化合物。利用红外光谱和核磁共振等测定了这些化合物的结构。用切段法测定了其中四个有机硅取代苯氧乙酸酯对小麦的生长刺激活性,发现它们对小麦的生长有一定的促进作用,其效果优于或接近于类似结构的植物生长调节剂2,4-D。
In this paper, a series of aryloxyacetoxy (methylene) silanes have been synthesized, most of which are new compounds which have not been reported in literature. The structures of these compounds were determined by infrared spectroscopy and nuclear magnetic resonance. The growth stimulating activity of four organosilicon-substituted phenoxyacetic esters on wheat was determined by the sectioning method and found that they had a certain promotion effect on the growth of wheat, and the effect was better than or similar to that of the similar structure of plant growth regulator 2,4-D.
