Water-soluble perfluorocyclobutyl (PFCB) aryl ether ionomers bearing sulfonic acid groups in the main chain and phosphonic acid end groups were prepared and used to modify the surfaces of mesoporous carbon materials containing dispersed zirconia nanoparticles. Ionomer surface grafting occurred via phosphonate bonding onto the zirconia particle surfaces.

Nitrophenols can be obtained in high yields via nitrosation-oxidation of phenols by 3methyl-1-sulfonic acid imidazolium chloride f[Msim]Clg as a new Br nsted acidic ionic liquid and NaNO2 at room temperature. In situ generation of HNO2 and a radical-cation mechanism via the nitrous acid catalyzed pathway appear to be applicable to phenol nitration using this reagent system.

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.
