Abstract. Arylsulfonylation reaction of benzothiazolin-2-one with p-methyl-benzenesulfochloride in the presence of triethylamine was carried out and formation of N-tosylbenzothiazol-2-one was observed.
It was shown that the synthesized N-tosylbenzothiazol-2-one and (N,N-dialkyl-aminoacetyl)-benzоthiazolin-2-ones have fungicidal activity against pathogenic fungi Fusarium oxysporum, aspergillus niger at different concentrations by disk diffusion method.
Keywords: Benzоthiazolin-2-one, N-tosylbenzothiazol-2-one, (N,N-dialkylaminoacetyl)-benzоthiazolin-2-one, Disc diffusion, fusarium oxysporum, aspergillus niger, fungicide, tebucanazole.
