Synthesis, characterization and application of poly(N,N'-dibromo- Nethylnaphthyl-2,7-disulfonamide) as an efficient catalyst for the acetylation and deacetylation reactions

In this work, a novel polymer namely poly(N,N'-dibromo-N-ethylnaphthyl-2,7- disulfonamide) (PBNS) is synthesized and characterized by studying its IR, 1H NMR, 13C NMR and thermal gravimetric analysis (TGA). This polymer is utilized as a highly efficient, heterogeneous and recyclable N-bromo reagent to catalyze acetylation of various compounds such as alcohols, phenols, thiol and amine with acetic anhydride under solvent-free conditions, and also it worthily catalyzes deacetylation of acetate esters in aqueous media.

ACYLSULFONAMIDES AND PROCESSES FOR PRODUCING THE SAME

The present disclosure relates to acylsulfonamides and processes for their preparation. The processes involve a target-guided synthesis approach, whereby a thioacid and a sulfonyl azide are reacted in the presence of a biological target protein, a Bcl-2 family protein, to form the acylsulfonamide.

Dependence of single-molecule conductance on molecule junction symmetry

The symmetry of a molecule junction has been shown to play a significant role in determining the conductance of the molecule, but the details of how conductance changes with symmetry have heretofore been unknown. Herein, we investigate a naphthalenedithiol single-molecule system in which sulfur atoms from the molecule are anchored to two facing gold electrodes. In the studied system, the highest single-molecule conductance, for a molecule junction of 1,4-symmetry, is 110 times larger than the lowest single-molecule conductance, for a molecule junction of 2,7-symmetry. We demonstrate clearly that the measured dependence of molecule junction symmetry for single-molecule junctions agrees with theoretical predictions.

SYNTHESIS AND SOME TRANSFORMATIONS OF (2,7-NAPHTHYLENEDITHIO)- AND (2,6-NAPHTHYLENEDITHIO)DIACETIC ACID

(2,7-Naphthylenedithio)- and (2,6-naphthylenedithio)diacetic acids were obtained from 2,7- and 2,6-naphthalenedisulfonic acids respectively and were oxidized to (2,7-naphthylenedisulfonyl)diacetic acids with hydrogen peroxide in acetic acid.The nitration of (2,6-naphthylenedithio)diacetic acid leads to the formation of (1,5-dinitro-2,6-naphthylenedithio)diacetic acid.
