Chromium trifluoride

Alkali metals and especially potassium cause their mixtures to detonate with chromium trifluoride and trichloride. There was also a detonation involving the violent combustion of lithium in contact with chromium trichloride in a nitrogen atmosphere. However, it should be noted that lithium (as well as titanium) is the only alkali metal which can burn in nitrogen. So the chloride implication is not demonstrated in this last case. 

The structure can be divided into infinite chains of linked octahedra. Those for Cr(III), joined through opposite corners, with a Cr—F—Cr angle of 160°, have a very similar orientation to that in chromium trifluoride itself. Similarly, those for Cr(II), joined through opposite edges, have the same orientation as in the distorted rutile structure of the difluoride.

The most important reactions of 4-arylazo-2-pyrazolin-5-ones are those with various salts to form metal complexes. These products are of great importance in the dye industry and will be discussed more completely in the section devoted to dyes. Chromium complexes are prepared by reaction of a 4-arylazo-2-pyrazolin-5-one with inorganic compounds213,1457 including chromium sulfate475 and chromium trifluoride,1616 with organic chromium compounds, such as chromium...

The gas-phase reaction of benzotrichloride with hydrogen fluoride over a chromium trifluoride catalyst is claimed to give a 93% yield of benzotri-fluoride, and pentafluorobenzaldehyde reacts with sulphur tetrafluoride to give a-jtf-heptafluorotoluene, C,Fj-CFjH (see also Vol. 1, p. 208), a better route to which apparently involves the fluorination of 2,3,4,5,6-pentafiuoro-benzal chloride. Bromination of the heptafluoro-compound gives perfluoro-...
