Thianes not containing 4-OH or 4-CO groups are oxidized by wet bromine predominantly to equatorial thiane 1-oxides. The reaction is assumed to proceed by way of an equatorial electrophilic attack by hypobromous acid at the S atom. An electronic interpretation is given of the steric course of ele...detailed
The present study reports a DSC study of the sulfur heterocyclic compounds: 2,2’-bithiophene [492-97-7]; 2,5-thiophenedicarboxylic acid [4282-31-9]; 3-acetylthiophene [1468-83-3]; 2-thiopheneacetic acid [1918-77-0]; 3-thiopheneacetic acid [6964-21-2]; 1,4-dithiane sulfone [139408-38-1]; 1,3-oxa...detailed
Electrochemical oxidation of 4-(p-chlorophenyl)thiane in aqueous organic solvents gave selectively the trans-sulfoxide by bromonium ion mediation. A preferential formation of the cis-sulfoxide was attained under acidic electrolyses.detailed
A thermophysical study of thiane sulfone, 1; 1,3-dithiane sulfone, 2; and 1,3-dithiane sulfoxide, 3 in the temperature intervals between T=268 K and their respective melting temperatures has been carried out. The experimental values for the mole fraction, temperature, enthalpy and entropy of fus...detailed
