Abstract:

The interaction of alkyl(4-X-2,3,5,6-tetrafluorophenyl)sulphanes (X = H, CF3) containing difluoromethyl and benzyl groups as alkyl components with hydrogen peroxide in acetic or trifluoroacetic acid gave the corresponding sulphonyl derivatives. The effect of the acid used on the reaction result was established in the case of (difluoromethyl)[4-(trifluoromethyl)-2,3,5,6-tetrafluorophenyl]sulphane. The synthesis of 1-alkylsulphonyl-2,3,5,6-tetrafluorobenzenes scaling possibility to tens of grams was demonstrated. Product yields were 84-97%.

Under controlled experimental conditions [T=20°C, pH=7, reaction-time = 48h, herbicide/disinfectant molar ratios: 0.05 and 0.05×10−2], ametryn reactions with chlorine dioxide much slower than with sodium hypochlo

Abstract:

The dipole moments of substituted diphenyl disulphones I-III were measured in benzene solution and interpreted by the previously described graphical method. The results suggest an equilibrium of the ap and sc conformations in the ratio 3 : 1, at variance with various empirical rules and theories of the so-called gauche effect. A statistical treatment of X-ray data of various sulphonyl derivatives revealed essentially two preferred conformations: the more stable sc, with a broadened dihedral angle, and the less stable ap.

Piperidines serve as pivotal synthetic building blocks in the realm of drug design, with their derivatives forming essential parts of a wide range of drugs and alkaloids. This study presents a novel approach involving sulfonyl derivatives of piperidine-3-carboxylic acid, achieved through amide coupling with substituted sulphonyl chlorides. The synthesized compounds underwent characterization via IR, 1H NMR, 13C NMR and MS analyses. Specifically, a series of novel sulphonamides derived from 1-(tert-butoxycarbonyl)piperidine-3-carboxylic acid was synthesized, given the significance of sulphonami

Abstract:

Sodium salt of 3-(hydroxymethylene)-trans-hexahydro-2(3H)-benzofuranone has been found to be formed as the (Z)-isomer in solid state and to exist as the (E)-isomer or a mixture of the both isomers in polar solvents. Some sulphonates and carboxylates of (E)-3-(hydroxymethylene)-trans-hexahydro-2(3H)-benzofuranone and (Z)-3-(hydroxymethylene)-trans-hexahydro-2(3H)-benzofuranone have been prepared by reactions of the corresponding isomers of this sodium salt with sulphonyl and acyl chlorides, respectively. The configuration of the isomeric derivatives was confirmed by 1H and 13C NMR spectra.
