It can be used as a fluorinating reagent in organic syntheses (fluorination of alcohols, carboxylic acids or carbonyl compounds) and has advantages over sulfur tetrafluoride in that milder conditions can be employed and it is a liquid rather than …

The Raman spectrum of solid, dry tetraselenium tetranitride, Se <SUB>4</SUB>N <SUB>4</SUB>, has been recorded in the region of 30-1000 cm <SUP>-1</SUP>. The assignment has been made on the basis of slightly deformed D<SUB>2 d</SUB> symmetry, which is in agreement with the X-ray structure determination and the infrared spectrum.The position of tetrasulfide bond determined the prodrug's chemical stability. As shown in Data S1 and S2, three tetrasulfide diacids with tetrasulfide bonds located at different positions of ester bonds were synthesized and named β-4S, γ-4S, and δ-4S, respectively. Synthesis of α-4S was discontinued due to the poor chemical stability and ...Tetraselenium hexadecachloride: [SeCl 4] 4; Selenium dibromide: SeBr 2; Diselenium dibromide: Se 2 Br 2; Teteaselenium hexadecabromide : [SeBr 4] 4; Selenium dioxide: SeO 2; Selenium trioxide: SeO 3; Diselenium hexasulphide: Se 2 S 6; Tetraselenium tetrasulphide: Se 4 S 4; Tetraselenium tetranitride: Se 4 N 4For magnesium ion batteries (MIBs) to be used commercially, new cathodes must be developed that show stable reversible Mg intercalation. VS 4 is one such promising material, with vanadium and disulfide anions [S 2] 2-forming one-dimensional linear chains, with a large interchain spacing (5.83 Å) enabling reversible Mg insertion. However, little is known about the details of the redox ...
