Arsenic Trifluoride, AsF3, is formed when fluorine reacts with arsenic trichloride 1 or with the arsenides of the alkali or alkaline earth metals 2 by the action of anhydrous hydrofluoric acid or of acid fluorides on arsenious oxide 3 by the action of certain metallic fluorides, for example silver or lead fluoride on arsenic trichloride,4 or of ammonium fluoride on arsenic tribromide B and by the action of iodine pentafluoride on arsenic.6... 

Arsenic trifluoride, ASF3, a molecular species, is synthesized from AS2O3 and anhydrous HF. Antimony trifluoride, SbF3, can be made by the action of aqueous HF on Sb203. Both fluorides are important agents for fluorination of chlorinated substrates. 

Writing formulas for molecular compounds is usually straightforward. Thus the name arsenic trifluoride means that there are one As atom and three F atoms in each molecule, and the molecular formula is ASF3. Note that the order of elements in the formula is the same as in its name. 

Solid S8(AsF3)2 has been shown to react with gaseous tetrafluoroethylene at room temperature and moderate pressure to give arsenic trifluoride,... 

Poly(/7-phenylene) was found to be processible when the polymerization was carried out in an arsenic trifluoride (ASF3) solution, using AsFs gas as the polymerizing reagent. At a temperature between 25°C and — 90°C, benzene or its derivatives polymerize and yield a homogeneous solution. However, no data concerning the structure, the properties or the polymerization mechanisms have been reported [28]. 

Arsenic forms a volatile trifluoride, ASF3, and a fairly volatile trichloride, ASCI3, which fumes in air. The latter is prepared by passing dry hydrogen chloride over arsenic(lll) oxide at 500 K ... 

Arsenic forms two fluorides, AsF3 and AsF5, both being produced by direct combination of the elements at ordinary temperature.1 The reaction renders the mass incandescent. The trifluoride is a colourless liquid, and the pentafluoride a colourless gas, both of which fume in contact with air.
