Sticks and bonds: Surface-modifying agents can be functionalized with ionic groups that enable high exhaustion from a processing bath through electrostatic self-assembly. Using cyclic oniums as the ionic functional groups, thermally induced ring-opening converts the ionic bonds to covalent bonds, thus lending permanency to the modification of the surface.

We have developed a green and facile approach for the straightforward installation of isoindolinone skeletons via a tandem reaction of 2-cyanobenzaldehydes and α,β-unsaturated ketones/esters. In the presence of catalytic amounts of the organocatalyst, fluorous phosphine, in green solvents at rt, a variety of isoindolinones were obtained in good to excellent yields without tedious column chromatography. Moreover, both the catalyst and the solvents could be recycled, which greatly reduced the consumption and waste of resources. The simplicity of manipulation, high efficiency of resource utilization and environmentally benign characteristics enable this protocol to have broad applications in the synthesis of isoindolinones, especially those for drug discovery.

Bis[2-(perfluoroalkyl)ethyl]cyclopentadienes were synthesized from lithium [2-(perfluoroalkyl)ethyl]cyclopentadienides and 2-(perfluoroalkyl)ethyl triflates as mixtures of four regioisomers, structure of which was determined by 1H and 13/

Polyhydroxamate chelators containing fluoro substituents are of interest as potential extractants for actinides in separations involving supercritical carbon dioxide. In this context, we have developed three new reagents 1, 2, and 3, that allow the efficient incorporation of an N-fluoroalkyl hydroxamate moiety onto a variety of substrates using acylation, alkylation, and Michael addition strategies.

Fluorinated building blocks, 2-(perfluorohexyl)ethyl triflate (11a) and 2-(perfluorooctyl)ethyl triflate (11b) were prepared from the corresponding fluoroalkanols and triflic anhydride. Fluorinated triflates 11 were employed for the preparation of bis(pol
OXYDATION ANODIQUE DE IODOPERFLUOROALCANES DANS LES ACIDES PERFLUOROALCANESULFONIQUES. PREPARATION DE NOUVEAUX ESTERS SULFONIQUES TOTALEMENT FLUORES RFSO3R'F A LONGUES CHAINES

, p. 487 - 492 (2007/10/02)
Perfluorinated sulphonic esters RFSO3R'F and fluorosulphates FSO3R'F, are easily obtained by anodic oxidation of iodoperfluoroalkanes R'FI in perfluoroalkene sulphonic acids RFSO3H (RF=CF3, C2F5, C4F9) and fluorosulphuric acid.With di-iodo compound I(CF2)4I, the mono and the diester can be selectively obtained.The alkaline hydrolysis of these esters produces perfluorinated carboxylic compounds.Polyfluorinated iodide R'FCH2CH2I are also oxidized in similar conditions.The mechanism of the electrolytic reaction is discussed.
