Carbonyl fluoride - Wikipedia
Carbonyl fluoride is a chemical compound with the formula C O F 2. It is a carbon oxohalide. This gas, like its analog phosgene, is colourless and highly toxic. The molecule is planar with C2v symmetry, bond lengths of 1.174 Å (C=O) and 1.312 Å …
Visible-Light-Mediated Liberation and In Situ Conversion of Fluorophosgene
2018年9月14日 · Fluorophosgene was liberated by the photocatalytic reduction of a simple aryltrifluoromethoxyether. This highly reactive species was used for the synthesis of cyclic carbonates, carbamates and urea derivatives.
Metabolism and Toxicity of Fluorine Compounds - PMC
Fluorine has many beneficial features and applications but can cause toxicity at high doses. Herein, we describe its chemical properties and benefits to agrochemical design as well as potential metabolic liabilities and exposure assessment in vivo.
Visible‐Light‐Mediated Liberation and In Situ Conversion of Fluorophosgene
Transient spectroscopic investigations suggest the formation of a catalyst charge‐transfer complex‐dimer as the catalytic active species. Fluorophosgene as a highly reactive intermediate, was indirectly detected via its next downstream carbonyl fluoride intermediate by NMR.

To circumvent this, the in-situgeneration of gaseous fluorophosgene from triphosgene, dinitrotrifluoromethoxybenzeneits conversion by fluoride into the OCF.
A deeper insight into direct trifluoromethoxylation with ...
2010年2月1日 · Commercially available fluorides (silver fluoride and n-tetrabutylammonium triphenyldifluorosilicate), combined with TFMT, allow a simple generation, in situ, of silver and n-tetrabutylammonium trifluoromethoxides which were able to react with electrophilic substrates.
Direct Trifluoromethoxylation without OCF3-Carrier through In …
An efficient atom economical trifluoromethoxylation method was developed with no need for trifluoromethoxylation reagent. This method relies on the in-situ generation of fluorophosgene and its conversion into OCF 3 anion to achieve nucleophilic substitution on a series of alkyl iodides. No articles found.
