摘要
以取代苯酚为原料亲核取代制得取代苯氧乙酸,采用硅胶负载四氯化锡为催化剂,二甲苯为溶剂,与二乙氨基乙醇发生酯化反应合成了6个苯氧乙酸二乙氨基乙醇酯衍生物。利用IR、1HNMR、13CNMR和MS对其结构进行了表征。初步的活性测试表明:与2,4-D(2,4-二氯苯氧乙酸)相比,大多数目标化合物均可促进玉米幼苗生长,提高玉米幼苗的硝酸还原酶活性,其中2-溴苯氧乙酸二乙氨基乙酯的处理质量浓度为20 mg/L时玉米幼苗硝酸还原酶活性最高。
Using substituted phenol as starting compound, substituted phenoxyacetate was prepared through nueleophilic substitution. Then, with stannic chloride loaded silicone as catalyst and dimethylbenzene as solvent, six (diethylamino)ethyl phenoxyacetate derivatives were synthesized through esterification reaction with 2-( diethylamino )ethanol. The title compounds were fully characterized by means of IR, ^1HNMR,^13CNMR and MS. Compared with 2,4-D,most title compounds have better bioactivity for promoting corn seedling growth or improving Under the mass concentration of 20 mg/L, the nitrate reductase activity phenoxyacetate was the highest. the nitrate reductase activity. of 2-bro-(diethylamino) ethyl
