SYNTHESIS AND ROOT-FORMING ACTIVITY OF DITHIOCARBAMATES BASED ON THE 2-(METHYLAMINO)ETHANOL AND QUINOLINE-8-OL

Abstract

New biologically active potassium and sodium dithiocarbamates were synthesized by the interaction of 2-(methylamino)ethanol and quinoline-8-ol with carbon disulfide in the presence of solutions alkali in ethanol at room temperature. As a result of the reaction sodium 2-hydroxyethyl(methyl)carbamodithioate (70%) and potassium O-quinolin-8-yl-carbonodithioate 2 (86%) were obtained. The structure of the synthesized compounds was established based by the data of elemental analysis, IR and NMR (1H and 13С) spectroscopic data. Field tests showed that the treatment of seedlings with dithiocarbamates activates the formation of the root system and shoots in comparison with the control group. The most effective was potassium O-quinolin-8-yl-carbonoditioat, which at a concentration 0.01% obtaind profound results in terms of root length about – 8 cm, the average number of formed shoots – 1,6, and an average length of the shoots at 1,4 cm.
