A series of 1,3-pentanodione derivatives were synthesized. Some derivatives showed good herbicidal and moderate fungicidal activity in the preliminary screening test.
A series of new substituted benzimidazole and benzothiazole containing phenoxy moiety and halogenomethylsulfonyl groups were synthesized. Biological activity of synthesized compounds was evaluated in screening tests. The (R) enantiomers of benzothiazole derivatives containing difluoromethylsulfonyl groups in the benzene ring and phenoxy moiety in the imidazole sceleton exhibited good herbicidal activity.
A series of new substituted (R)-enantiomers of benzimidazole, benzoxazole and benzothiazole was synthesized and their biological activity was evaluated. Some derivatives with trifluoromethylsulfonyl groups in the benzene ring showed a good herbicidal activity in the preliminary screening test.
The synthesis of 4-dichloromethylsulfonyl-2-nitrophenylsulfenyl chloride and its transformation into new compounds with promising pesticidal activity is reported. The title compounds were obtained by a three-step synthesis, starting from 4-dichloromethylchlorophenyl sulfone. It was nitrated and then subjected to the SNAr reaction with sodium disulfide to give proper diphenyl disulfide, which was next chlorinated by chlorine. The obtained phenylsulfenyl chloride was transformed into sulfenamide derivatives by reactions with amines.
