Trifluoro methane, fluorinating

ESCA has been used to determine the molecular structure of the fluoride ion-induced tnmerization product of perfluorocyclobutene [74] and the products of the sodium borohydnde reduction of perfluoroindene [75] ESCA is also used to analyze and optimize gas-phase reactions, such as the bromination of trifluoro-methane to produce bromotrifluoromethane, a valuable fire suppression agent [76] The ionization energies for several hundred fluorine-containing compounds are summarized in a recent review [77]... 

The reaction of bis(2-methoxyethyl) ether (diglyme, 7) at 160°C results in elimination offluoro-methane, cyclization and substitution of three hydrogen atom by fluorine to give 2,2,3-trifluoro-1,4-dioxane (1).23S... 

A second important and useful compound is trifluoro(fluorooxo)methane, CF3OF (b.p. —95°), which is obtained by fluorination of CH3OH or CO by F2 in presence of AgF2. It is stable to 450° and is a reactive, strong oxidant which undergoes a wide variety of reactions, e.g. ... 

The use of trifluoro(fluoroxy)methane for the stereospecific introduction of a fluorine atom at the branching point of branch-chain sugars has been reported previously (see Vol. 9, p. 56). The fluorinated branched-chain derivative (403) has been converted into 3-C-acetoxymethyl-6-0-benzoyl-3-deoxy-3-fluoro-D-glucose,... 

Preparation.— Fluorination of diazo-ketones with trifluoro(fluoro-oxy)methane produces mainly a mixture of a,a-difluoro-ketones and a-fluoro-a-trifluoro-methoxy-ketones. ...
