investigated and an efficiency of subsequent reactions of the generated C(4)-lithio derivatives with electrophiles was shown to depend on the exploited deprotonating reagent. It was found that 4-(α-arylhydroxymethyl)sydnone imines, when used for pre-sowing treatment of corn seeds at very low doses (0.25-5 g t−1), promoted a plant growth up to 60%.
研究了六甲基二硅叠氮化锂(LHDMS),二异丙基酰胺锂(LDA),二乙酰胺锂(LDEA)和n -BuLi对N 6取代的亚砜亚胺的C(4)脱质子作用。研究了4-lithiosydnone亚胺的热稳定性,并证明了生成的C(4)-硫代衍生物与亲电试剂的后续反应效率取决于所开发的去质子化试剂。发现4-(α-芳基羟甲基)亚砜亚胺当用于极低剂量(0.25-5gt -1)的玉米种子的播种前处理时,促进植物生长高达60%。
