Cyclotetra- and cyclohexa-decane ring systems were prepared with CF2 groups spaced 1,4- and 1,6- for tetradecanes together with 1,5- and 1,6- for hexadecanes. These alicyclic systems were assembled by ring closing metathesis reactions of long terminal diolefins. Ring cyclisation by RCM was promoted by the introduction of the dithiane motif, using a sulfur compatible metathesis catalyst. This ga...

electrode potential of 2-(2,3-dihydroxy phenyl)-1,3-dithiane (dpd) was investigated by means of cyclic voltammetry (cv) at various potential scan rates. the calculated value was compared with the experimental value obtained by cyclic voltammetry (cv). all experiments were done in aqueous phosphate buffer solutions at different phs. the experimental redox potential of dpd was obtained to be 0.75...

The title compound, [SnBr4(C4H8S2)] {systematic name: catena-poly[[tetrabromidotin(IV)]-μ-1,4-dithiane-κ(2) S:S']}, represents the first 1,4-di-thiane complex with tin as coordination centre. The asymmetric unit consist of half a formula unit with the tin(IV) atom at the centre of symmetry at 0,0,1/2 (Wyckoff symbol b) and a centrosymmetric 1,4-di-thiane mol-ecule with the centre of symmetry in...

Many biological and geochemical questions remain concerning the structures, functions, and properties of naturally occurring high-molecular-weight (C40+) alkanes with various mid-chain alkylation patterns. Above C40, these alkanes are exceedingly difficult to separate and purify, and syntheses can be blocked by the low solubility of intermediates. To overcome these problems, a facile three-step...
