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 plantgrowth up to 60%.

representatives of ferrocenyl-containing mesoionic heterocyclic compounds were synthesized by the reaction of 4-lithium derivatives of sydnones and sydnone imines with ferrocenecarboxaldehyde. A series of 4-(α-hydroxy)- and 4-(α-methoxy)ferrocenyl-methyl derivatives of sydnones and sydnone imines, which were found in vegetation tests using seeds of corn cv. Krasnodarskaya 291 AMB, exhibit growth-regulating
通过苯乙烯酮和苯乙烯酮亚胺的4-锂衍生物与二茂铁甲醛的反应合成了含二茂铁基介离子杂环化合物的第一个代表。一系列 4-(α-羟基)- 和 4-(α-甲氧基)二茂铁基-甲基 苯乙烯和苯乙烯亚胺衍生物,在使用玉米种子的植被测试中发现。Krasnodarskaya 291 AMB 对除草剂甲磺隆具有生长调节和解毒活性。
