SYNS FLUORINE MONOXIDE FLUORINE OXIDE OXYGEN FLUORIDE... 

SYNONYMS difluoride monoxide, fluorine monoxide, fluorine oxide, oxygen fluoride. 

The oxides of fluorine are more correctly called oxygen fluorides because of the greater electronegativity of fluorine.

In research al the Institute or Radiochemistry. Karlsruhe, West Germany during Ihe early 1970s. investigators prepared alloys of Curium with iridium, palladium, plalinum. and rhodium. These alloys were prepared by hydrogen reduction of the curium oxide or fluoride in the presence of finely divided noble metals. The reaction is called a coupled reaction because the reduction of the metal oxide can be done in the presence of noble metals. The hydrogen must be extremely pure, w ith an oxygen content of less than 10 -s Inrr. 

An environmentally greener process for the synthesis of HFCs can be envisioned through an intermediate inorganic metal fluoride that is capable of fluor-inating a C-H bond of a desirable hydrocarbon and could be regenerated to the appropriate oxidized metal fluoride with oxygen and HF. The general synthetic approach is shown in equations (6a) and (6b) and the net reaction is shown in equation (6c). 

The platinum metal chalcogenides in general are easier to prepare than the corresponding oxides. Whereas special conditions of temperature and pressure are required to prepare many of the oxides, the platinum metals react most readily with S, Se, and Te. A number of additional differences concerning the chemistry of the chalcogenides and the oxides are summarized as follows The metal—sulfur (selenium, tellurium) bond has considerably more covalent character than the metal-oxygen bond and, therefore, there are important differences in the structure types of the compounds formed. Whereas there may be considerable similarity between oxides and fluorides, the structural chemistry of the sulfides tends to be more closely related to that of the chlorides. The latter compounds...
