•SbF5 complex and methyl fluoride, or by transmethylation with 2.

Common monofluoride are organofluorine compounds such as methyl fluoride and fluorobenzene.

This salt (2) is also formed, but more slowly, by reaction of methyl fluoride with the crystalline 1:1 complex of sulfolane and antimony pentafluoride.

Dielectric relaxation has been observed in gaseous methyl fluoride (CH3F) and fluoroform (CHF3).

The reactions of the molecular ion have been studied as a function of the ion kinetic energy for methyl fluoride and methyl chloride.

This behaviour is consistent with a C—Cl bond insertion mechanism of the type proposed previously for insertion reactions of Ln+ cations with hydrocarbons and methyl fluoride.

If the van der Waals interactions perturb the spin–orbital term in J, then 2J in fluoroform may well contain orbital contributions, as recently calculated for 2J in methyl fluoride.

Fluoride is also used non-systematically, to describe compounds which releases hydrogen fluoride upon acidification, or a compound that otherwise incorporates fluorine in some form, such as methyl fluoride and fluorosilicic acid.
