Difluoromethylation of (hetero)aryl chlorides with chlorodifluoromethane catalyzed by nickel
Nature Communications, 2018 Transformations with ClCF2H are very limited and normally involve a difluorocarbene intermediate. Here, the authors report a nickel-catalyzed difluoromethylation of aryl chlorides with chlorodifluoromethane via a difluoromethyl radical intermediate and ...

Polymer International, EarlyView.An overview and categorization of man‐made per‐ or polyfluoroalkyl substances (PFASs) including low‐molar‐mass and high‐molar‐mass fluorochemicals, and their international regulations is presented. Though certain PFASs are toxic, bioaccumulative and cross the human cellular membranes, others, such as fluoropolymers, are safe, reliable and involved in ...

Chemistry of (Z)-2H-Heptafluorobut-2-ENE [PDF]
, 1995 The research described within this thesis may be divided into four areas:1) The synthesis of (8) was investigated, and was shown to produce some novel by-products, including highly fluorinated dienes and even a triene.

Groundwater Monitoring &Remediation, EarlyView.Abstract Injectable colloidal activated carbon (CAC) has been commercially used to remediate per and polyfluoroalkyl substances (PFAS) in groundwater since 2016. The basis of the technology is enhanced PFAS retention within the aquifer from engineered increases in aquifer‐matrix sorptivity (“PFAS enhanced retention”), with re‐equilibration from the ...

Unique Reactivity of Fluorinated Molecules with Transition Metals
CHIMIA, 2014 Organofluorine and organometallic chemistry by themselves constitute two potent areas in organic synthesis. Thus, the combination of both offers many chemical possibilities and represents a powerful tool for the design and development of new ...
