N-Fluoro-bis[(trifluoromethyl)sulfonyl]imide: Interesting reactions involving nucleophilic attack on sulfonyl groups

N-Fluoro-bis[(trifluoromethyl)sulfonyl]imide (1) undergoes reaction with a variety of nucleophiles to give a number of interesting products. Under suitable conditions, the sulfonyl group on 1 is subject to nucleophilic attack forming N-fluoro-trifluoromethylsulfonyl amide (3) and Nu-SO2CF3. Surprisingly, 3 can also function as a weak nucleophile in the absence of other stronger bases.

Ten palladium(II) complexes bearing a pyrazolin-5-ylidene ligand have been synthesized by oxidative addition and silver carbene transfer pathways. The weakly bound acetonitrile ligand in the initially obtained trans-[PdBr 2(MeCN)(Pyry)] complex (6, Pyry = 1-phenyl-2,3-dimethylpyrazolin-5- ylidene) could be replaced by other donor ligands, and additional NHC ligands were introduced either by silver carbene transfer reactions or via reaction with in situ generated free carbenes. Using our previously reported 13C NMR-based electronic parameter, the pyrazolin-5-ylidene ligand is estimated to be among the most strongly donating ligands on our scale so far. The complexes obtained were employed as catalysts for the direct arylation of pentafluorobenzene with moderate to good yields under optimized conditions.

Novel heteroaryl triflones including oxindole, pyrazolone, pyridine, and quinoline derivatives have been regioselectively synthesized by LDA-mediated thia-Fries rearrangement for the first time. These reactions are also the first examples of the application of anionic thia-Fries rearrangement in heteroaromatic compounds.
Palladium-catalyzed coupling of pyrazole triflates with arylboronic acids
Dvorak, Curt A.,Rudolph, Dale A.,Ma, Sandy,Carruthers, Nicholas I.
, p. 4188 - 4190 (2007/10/03)
A general protocol for the palladium-mediated Suzuki coupling reaction of pyrazole inflates and aryl boronic acids has been developed. The use of additional dppf ligand was determined to increase product yields allowing for the use of a broad range of rea
