The effect of triphenylphosphine on ring-opening of aliphatic epoxides with potassium fluoride-poly(hydrogen fluoride)

The ring-opening reaction of aliphatic epoxides with potassium fluoride-poly(hydrogen fluoride) is enhanced by a catalytic amount of triphenylphosphine. It is assumed that phosphonium fluoride species formed from triphenylphosphine work as fluorinating ag
Enantioselective ring-opening of epoxides by HF-reagents: Asymmetric synthesis of fluoro lactones
Haufe, Günter,Bruns, Stefan,Runge, Martina
, p. 55 - 61 (2007/10/03)
The asymmetric ring opening of meso- and racemic-epoxides with different HF-reagents mediated by enantiopure (salen)chromium chloride provides optically active fluorohydrins with maximum 90% e.e. This reaction as well as lipase-catalyzed deracemization of
Regioselectivity of the ring opening of propene oxides bearing electron-withdrawing substituents at the methyl group with Olah's reagent
Skupin, Rolf,Haufe, Guenter
, p. 157 - 165 (2007/10/03)
The regiochemistry of the hydrofluorination of terminal epoxides with Olah's reagent (Py·9HF) is dependent on the electron-withdrawing character of the β-substituents. Phenoxy ethers with different substitution patterns of the aromatic ring and several N-heterocycles were examined as β-substituents.
