It spontaneously reacts with chlorine and fluorine to form hydrogen chloride and hydrogen fluoride, respectively.[24] The reactivity of H2 is strongly affected by the presence of metal catalysts. Thus, while mixtures of H2 with O2 or air combust readily when heated to at least 500 °C by a...

The addition of hydrogen fluoride is highly regio-selective for both substrates. It was found to be stereospecific for cis-2-amido-aziridines since threo-β-fluoro α-amninoacid amides were exclusively obtained from the ring-opening with Olah's reagent. Cis-2-cyanoaziridines gave in all cases...
A process is disclosed for the manufacture of CF3CH2CHF2 and CF3CHFCH2F. The process involves (a) reacting hydrogen fluoride, chlorine, and at least one halopropene of the formula CX3CCl═CClX (where each X is independently F or Cl) to produce a product

High-temperature molecules like lithium fluoride (LiF) can be trapped in matrices by evaporating the molecule from the crystalline solid in a Knudsen cell at high temperature or by reacting lithium atoms with fluorine molecules during condensation. The latter method has been used to synthesize the ...
