We develop coarse-grained force fields for poly (vinyl alcohol) and poly (acrylic acid) oligomers. In both cases, one monomer is mapped onto a coarsegrained bead. The new force fields are designed to match structural properties such as radial distribution functions of various kinds derived by atomistic simulations of these polymers. The mapping is therefore constructed in a way to take into acc...

Redox-neutral tetrafluoroethylation of aryl alkynes with 1,1,2,2-tetrafluoroethane sulfonic acid leading to α-tetrafluoroethylated acetophenones is described in the Full Paper by Takuji Kawamoto and co-workers on page 9529 ff. The reaction proceeds via formation vinyl tetrafluoroethanesulfonates followed a radical tetrafluoroethylation.

In this work agar- and borax-based hydrogels with without the addition of poly(vinyl alcohol) (PVA) at different concentrations were synthesized. Hydrogels modified by same amount acetylsalicylic acid (ASA) which exhibits antithrombotic properties. The effect modification ASA on properties was analyzed.

Dihydropyrans have been prepared by the cyclisation of easily accessible propargyl vinyl ethers with (TFP)AuCl/AgBF(4) as a catalyst in high yields. These compounds undergo acid-catalysed rearrangement into cyclopentenone derivatives.

The synthesis of the marine natural product 1,6Z,9Z,12Z,15Z-octadecapentaen-3-one (1) has been achieved by two different routes starting from the ethyl esters of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), respectively. Using EPA ethyl ester as starting material the polyunsaturated vinyl ketone lipid 1 was obtained in 17% overall yield.

Novel ion-gel films containing an amino acid ionic liquid were fabricated by free radical polymerization of vinyl monomers. These high strength materials demonstrated superior CO2 permeability and separation performance.
