FLUORINATION WITH POSITIVE FLUORINE GENERATED FROM ISOELECTRONICALLY RELATED REAGENTS
Cartwright, M.,Woolf, A. A.
, p. 101 - 122 (2007/10/02)
Compounds such as PhIF2, PhPF2 and XeF2, which have been used previously as unrelated fluorinating agents, are shown to be periodically related as isoelectronic molecules E3AF2 of trigonal-bipyramidal shape, where E represents a bonded or nonbonded electron pair and A a main Group V-VIII element.These compounds are arranged in order of halogenating ability by estimating the magnitude of reduction couples, approximated by ΔH0f(E3AF2-E3A), or by noting the direction of redox reactions involving the couples.The A sequence deduced Kr>Xe ca.Cl>Br>I>S>Se>Te-As-Sb>P agrees with the limited experimental data available.Evidence for an ionic mechanism involving 'onium' monohalide ions is given for halogenations with these reagents when carried out under "Friedel-Crafts" conditions although no stable salts containing these ions have as yet been isolated because of intramolecular halogenation.These ions act as sources of positive fluorine.The use of ring deactivated reagents to achieve halogenation is discussed.
The chloramination of some substituted arsines
Sisler, Harry H.,Stratton, Cedric
, p. 2003 - 2008 (2007/10/05)
The reactions of triphenylarsine and diphenylchloroarsine with chloramine and with mixtures of chloramine and ammonia have been carried out and a variety of aminoarsonium chlorides and cyclic arsenonitriles prepared. Similar compounds have been derived by the ammonolysis of di- and trichlorophenylarsanes. It has been shown that chloramination, like chlorination, of phenylarsines results, under some conditions, in the fission of some of the arsenic-phenyl bonds and the elimination of chlorobenzene.
