Nitrogen-diluted chlorine trifluoride reacts with unsaturated compounds, such as ethene, vinyl chloride, and vinyl fluoride, in the vapor phase at 70-200 C to give a mixture of Mar-kovnikov-type chlorine monofluoride addition products to the C = C bonds and products of... 

Chlorine monofluoride is a colorless gas that condenses to a very pale yellow liquid. It is prepared by the interaction of chlorine trifluoride and chlorine or by heating chlorine and fluorine together in a 1 1 ratio. It can be used to saturate multiply bonded systems or oxidize coordinatively unsaturated central atoms. Scheme 8 illustrates some types of CIF reactivity. 

Plan We first write the balanced equation. From its name, we know that chlorine trifluoride consists of one Cl atom bonded to three F atoms, CIF3. Elemental chlorine and fluorine refer to the diatomic molecules CP and F2. All the substances are gases. To find the limiting reactant, we compare the number of molecules we have of each reactant, with the number we need for the other to react completely. The limiting reactant limits the amount of the other reactant that can react and the amount of product that will form. 

Practice Exercise Draw the Lewis structure for chlorine trifluoride (CIF3). (AH fluorine atoms are bonded to the central chlorine atom.)... 

Earlier in this ehapter, the structure of PTFE was likened to a carbon rod completely blanketed with fluorine atoms which render the C-F bond impervious to solvent attack. This postulate has been proven by testing the effect of almost all common solvents on this polymer. There are no known solvents for PTFE below its melting point. PTFE is attacked only by molten alkali metals, chlorine trifluoride, and gaseous fluorine. Attack by alkali metals results in defluorination and surface oxidation of PTFE parts which is a convenient route to render them adherable. 

On the other hand, oxidizing fluonnating agents like silver difluoride, xenon difluoride, or bromine trifluoride replace one chlorine group and then cleave the sulfur-nitrogen bond [56],... 

Thus, a stable derivative of phosphorus triamide, P(NH2)3, could not be obtained. Such expectations were encouraged by recent work of Kodama and Parry (12), who succeeded in ammonolyzing phosphorus trifluoride-borane, F3P.BH3, with formation of a stable phosphorus triamide-borane, (H2N)3P.BH3. Ammonolysis of boron- or phosphorus-fluorine rather than -chlorine bonds is advantageous, since ammonium fluoride is insoluble in liquid ammonia and can easily be separated, while ammonium chloride is readily soluble. 

Boron trifluoride and boron trifluoride-diethyl ether complex can be used as a source of fluoride ions in the presence of hypobromites and hypochlorites, e.g. methyl hypobromitc, tert-butyl hypobromite, methyl hypochlorite in carbon tetrachloride at 25 C. The addition of bromine monofluoride" and chlorine monofluoride" to various alkenes is accompanied by the formation of the corresponding alkoxybromides and alkoxychlorides which hinder the isolation of the halofluorinated products.57 jV-Bromo- and A -chloro-substiluted alkyl- and arylamines. -amides, and -imides, A -chloro-A,-methylamine, A -bromo-A -methylamine, A -chloro-A, /V-dimethylamine, A-bromo-A.A-dimethylamine, ACV-dichloro-A -methylamine, V,fV-dibromo-,V-mcthylaminc, A -bromosuccinimide, -V-chlorosuccinimide, Af-bromoacct-amide, A.A -dichlorourethane, can be used in the reaction instead of the hypohalites. The reactions with various alkenes conducted in dichloromethane at room temperature in the presence of boron trifluoride-diethyl ether complex produce bromofluoro and chlorofluoro addition products in 40-80 % yield. However, the reactions are complicated by the addition of A -halo-succinimides and Af.A-dichlorourcthane to the C = C bonds.58... 

The addition of chlorine monofluoridc across the C = 0 bonds in difluorophosgene, per-fluoroacyl fluorides, and perfluoroketones with the formation of hypochlorites occurs only in the presence of the catalysts potassium fluoride, rubidium fluoride, cesium fluoride80,81 or the strong Lewis acids hydrogen fluoride, boron trifluoride, or arsenic(V) fluoride.82 The cesium fluoride catalyzed reactions are carried out in an autoclave for 2-3 hours at — 20"C or left overnight.80... 

When chlorine is added to olefinic double bonds in the presence of hydrogen fluoride and aluminum trifluoride as catalyst addition, substitution and isomerization occurs17-25-26. Detailed investigations have been undertaken to elucidate the reaction pathways and the influence of the catalyst system on the prod uct distribution in the case of tetrachloroethene and chlorine.17... 

The addition of hydrogen fluoride to the double bonds of chlorinated alkenes in the presence of an aluminum trifluoride catalyst is effective and has found broad synthetic application (Table 2). It proceeds so effectively that it is sometimes used to remove fluoroalkenes in crude product mixtures by adding hydrogen fluoride in this way.27 28... 

First, antimony trifluoride is treated with chlorine and thus antimony dichlorotrifluoride is formed. This compound catalyzes intramolecular rearrangement of fluorine with the simultaneous allylic shift of the double bond. As in Explanation 99, the tendency is to accumulate fluorine at the same carbon. The product is 1-chloroperfluoropropene Z [756].
