The reactivity of isocyanides with pentafluoropyridine

Monatshefte Für Chemie, 2021
Reactivity of some isocyanides with pentafluoropyridine under basic conditions in dry dimethyl sulfoxide was investigated. The reaction of pentafluoropyridine with toluenesulfonylmethyl isocyanide (TosMIC) was less selective, but the reactions of other isocyanides with pentafluoropyridine gave the desired 2,3,5,6-tetrafluoro-N-substituted ...

Macrocycles from pentafluoropyridine and tetrafluoropyrimidine

Journal of Fluorine Chemistry, 2008
Macrocycles were synthesised by sequential nucleophilic aromatic substitution processes involving pentafluoropyridine and tetrafluoropyrimidine and various diamines as the structural components.

Survey reactivity of some N-aryl formamides with pentafluoropyridine

Journal of Fluorine Chemistry, 2015
Abstract Chemo selectivity of some N -aryl formamides with pentafluoropyridine under basic conditions in dry THF was investigated. The aromatic nucleophilic substitution of pentafluoropyridine with enol–imines derived from N -aryl formamides occurs at the 4-position of pyridine ring by both oxygen and nitrogen site of enol–imines depending on the ...

Survey reactivity of 5-substituted tetrazoles toward pentafluoropyridine

Journal of Fluorine Chemistry, 2019
Abstract Reactivity of some 5-substituted tetrazoles with pentafluoropyridine under basic conditions in acetonitrile was investigated. The reaction of pentafluoropyridine with tetrazoles regioselectively occurs at the 4-position of pyridine ring by N2 in the tetrazole ring.

Survey of reactivity of some enolates with pentafluoropyridine and 4-phenylsulfonyl-2,3,5,6-tetrafluoropyridine

Journal of Fluorine Chemistry, 2013
Abstract Site reactivity of some enolates derived from acetyl attached to the aromatic and heteroaromatic system with pentafluoropyridine and 4-phenylsulfonyl-2,3,5,6-tetrafluoropyridine under basic conditions in dry THF at reflux was investigated. The aromatic nucleophilic substitution of pentafluoropyridine with enolates occurs at the 4-position of

The gas phase photolysis of pentafluoropyridine

Journal of Photochemistry, 1980
Abstract Continuous photolysis of pentafluoropyridine produced the Dewar isomer which underwent rearomatization with a half-life of about 5 days at room temperature. Flash photolysis of pentafluoropyridine gave two transients which decayed with half-lives of 22 ms and 3 ms respectively.
