Abstract: The reactions of halogenated alcohols, hydroxy ketones, and unsaturated alcohols with 3-[(chloroformyl)methyl]-2-benzothiazolinone or with 4-chloro-3-[(chloroformyl)methyl]-2-benzothiazolinone gave the corresponding 3-alkoxycarbonylmethyl-2-benzothiazolinones. The structure of the products was confirmed by means of UV, IR, and 1H NMR spectra. The tests performed on Triticum aestivum L. proved the highest stimulating effect for 4-chloro-3-(3-oxa-5-hexyloxycarbonylmethyl)-2-benzothiazolinone (∆/ = 68.08 %).
