O-Trifluoromethylation of Carboxylic Acids via the Formation and Activation of Acyloxy(phenyl)trifluoromethyl-λ3-Iodanes

Here we report the challenging O-trifluoromethylation of carboxylic acids via the formation and activation of acyloxy(phenyl)trifluoromethyl-λ3-iodanes. The method provides an easy access to various potentially valuable and hitherto elusive trifluoromethyl carboxylic esters. A remarkably wide range of substrates with commonly encountered functional groups are compatible with this reaction, including aromatic and aliphatic carboxylic acids, as well as Food and Drug Administration (FDA) approved drugs and pharmaceutically relevant molecules. The reaction mechanism and the origins of the enhanced reactivity by zinc chloride (ZnCl2) were discussed from experimental evidence and density functional theory (DFT) calculation.

Controlled copolymerization of n-butyl acrylate with semifluorinated acrylates by RAFT polymerization

A new class of well-controlled semifluorinated copolymers were successfully synthesized via RAFT polymerization. We found that ESI-TOF MS was particularly useful for readily analysing our semifluorinated copolymers. The reactivity ratios of each pair of co-monomers are close to one.

A rational approach to activated polyacrylates and polymethacrylates by using a combination of model reactions and SET-LRP of hexafluoroisopropyl acrylate and methacrylate

A new class of activated polyacrylates was elaborated by a combination of model reactions and SET-LRP of hexafluoroisopropyl acrylate and methacrylate.

SET-LRP of semifluorinated acrylates and methacrylates

For the first time SET-LRP of 1H,1H,2H,2H-perfluorooctyl acrylate, 2,2,3,3,4,4,4-heptafluorobutyl acrylate, 1H,1H,5H-octafluoropentyl acrylate and 1H,1H,5H-octafluoropentyl methacrylate in 2,2,2-trifluoroethanol as the solvent at 25 °C for acrylates and at 50 °C for methacrylate was accomplished.
