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%.
