Hazard Predictions

• Generates heat: Exothermic reaction at ambient temperatures (releases heat)

Reactions between certain fluorinated hydrocarbon compounds and metal hydrides may proceed by proton abstraction from an atom adjacent to fluorine. These reactions may be exothermic (it is unknown whether such reactions would yield the 100 cal./ gram threshold). Caution should be used before proceeding. Further research of comparable examples in the literature or very small scale, carefully controlled experiments may be needed to fully assess compatibility.

The para-fluorine atom of pentafluoropyridine is susceptible to nucleophilic attack, and can be replaced by hydrogen using lithium aluminum hydride, producing 2,3,5,6-tetrafluoropyridine (R. E. Banks et al., J. Chem. Soc., 575 (1965)).

Benzotrifluoride (trifluorotoluene) is not reduced by lithium aluminum hydride (Boudakian, M. M. 2000. Fluorinated Aromatic Compounds. Kirk-Othmer Encyclopedia of Chemical Technology. (Online)).
