Abstract: 3-Phenoxycarbonylmethyl-2-benzothiazolines and their 4-chloro derivatives have been synthesized by the reaction of (2-oxobenzothiazolin-3-yl)acetyl chloride and (4-chloro-2-oxobenzothiazolin-3-yl)acetyl chloride, respectively, with phenols. Tests performed on Triticum aestivum L. have proved the stimulation activity of 7.6 % to 52.18 %. UV and IR spectra of the synthesized compounds have been measured. On the basis of them, an existence of intramolecular donor-acceptor interaction has been considered.
