Ohne viel Aufwand dank Kupfer: Ausgehend von der Beobachtung, dass 1 durch bestimmte Metalle reduziert werden kann, wurde eine einfache Methode zur Synthese trifluormethylierten Heteroarenen unter milden Bedingungen entwickelt (siehe Schema). Es wird angenommen, Kupfer das Substrat über einen Einelektronentransfermechanismus reduziert, und CuCF3 ist die wahrscheinlichste Zwischenstufe dieser Reaktion.

The CF3 radical was generated from the reaction of S-(trifluoromethyl)diphenylsulfonium triflate with Na2S2O4 or HOCH2SO2Na under suitable conditions without further reduction. Based on this, a method for synthesis α-trifluoromethylated ketones has been successfully developed.

Impressive progress has been achieved during the past decade in incorporation of various fluroinecontaining groups, especially lightly fluorinated into organic compounds. Among them, introduction difluoromethyl group a compound commonly brings about many special and important effects. Two major strategies have developed: (1) direct transfer CF2H target molecules (direct difluoromethylation); (2) functionlized moiety substrates followed by subsequent transformation functional hydrogen or...
The 20 π-electron nonaromatic isophlorin 2 had been successfully isolated and thoroughly characterized was formed by reduction of Cu(II) β-tetrakis(trifluoromethyl)-meso-tetraphenylporphyrin (Cu1) with activated zinc powder. However, the reaction utilizing Ni(II) (Ni1) as a substrate Na2S2O4 reductant at 100 °C resulted in formation porphydimethene 5. Subsequent N-methylation led to N-dimethylated 3 or N-tetramethylated 4 depending on choice base used.
Abstract Presented is a novel intermolecular radical trifluoromethylfluorosulfonylation of unactivated alkenes under mild reaction conditions with good functional‐group tolerance in the most atom‐economic manner by using readily available Ag(O 2 CCF SO F) and N ‐fluorobenzenesulfonimide (NFSI). Both trifluoromethyl sulfonyl groups products originate from F).
Electrically conductive nanocrystalline diamond films (approximately 750 to 1000 nm thick) were deposited on conducting Si and W substrates from gas mixtures using plasma-enhanced chemical vapor deposition. Such are continuous over the surface nanometer smooth. The grain size is 3 10 nm, boundaries 0.2 0.5 wide (two carbon atoms). Nitrogen appears substitutionally insert into film concentration scales with added source mixture up about 5% level. nitrogen-incorporated void of pinholes cracks,...
A versatile and general zinc-mediated intermolecular reductive radical fluoroalkylsulfination of unsaturated C-C bonds has been developed using readily available fluoroalkyl bromides 1,4-diazabicyclo[2.2.2]octane-bis(sulfur dioxide) adduct (DABSO) with wide substrate scope excellent functional group tolerance. Sulfur dioxide anion generated in situ from the reduction sulfur zinc may be involved reaction mechanism.
Reaction of unactivated alkenes affords various fluoroalkyl-containing alkyl sulfonyl fluorides with good functional group tolerance under mild conditions.
