Activation of the C-F bond of benzylic fluorides was achieved using 1,1,1-tris(hydroxymethyl)propane (2) as a hydrogen bond-donating agent. Investigations demonstrated that hydrogen bond-donating solvents are promoting the activation and hydrogen bond-accepting ones are hindering it. However, the reaction is best run under highly concentrated conditions, where solvents cannot interfere with the...

x. The toxicity and action offluenethyl or 2-fluoroethyl(4-biphenylyl ) acetate, several other monofluoroethyl esters, monofluoroethanol, monofluoroacetic acid and fluoroacetamide were studied in mice, houseflies (Musca dornestica L.) and twospotted spider mites (Tetranychus urticae Koch). 2. Toxicity varied markedly with the test compound, method of application and biological species. Generall...

Organofluorine is a weak hydrogen-bond (HB) acceptor. Bernet et al. have demonstrated its capability to perturb OH···O intramolecular hydrogen bonds (IMHBs), using conformationally rigid carbohydrate scaffolds including levoglucosan derivatives. These investigations are supplemented here by experimental and theoretical studies involving six new levoglucosan derivatives, and complement the findi...

Perfluorinated compounds (PFCs) are man-made organofluorine chemicals manufactured and marketed for their stain-resistant properties. Polychlorinated biphenyls (PCBs) are anthropogenic organochlorine compounds previously used in various industrial and chemical applications prior to being banned in the Western world in the 1970s. Both PFCs and PCBs are persistent contaminants within the human or...

Per- and polyfluoroalkyl substances (PFAS) constitute a group of organofluorine chemical synthetic compounds widely used in industries manufacturing due to their hydrophobic properties. However, PFAS have been found cause negative human health outcomes. Therefore, strong interest the possible removal these from wastewater (WW) has shown. This work aims present systematic analysis scientific lit...
