The Chloramination of Some Aminophosphines

Hydrogen-1, carbon-13, and phosphorus-31 nuclear magnetic resonance spectral studies of some phenyl- and perfluorphenyl-substituted aminophosphines and aminophosphonium salts

“…It is important to note that in all cases, the quantities calculated by our method are quite comparable in accuracy to those that would be expected from a comparable full SCF calculation. This finding is in accord with our previous study of the series of group 4 homonuclear, diatomic molecules.1 The cost advantage of the pseudopotential method may be estimated on the assumption that the computation time increases as the fourth power of the size of the basis set. This means that an exactly equivalent full SCF computation for PF3 would take about 5 times longer than the pseudopotential computation, whereas, for PI3, the increase in time would be around 1300-fold!…”

“…(Levason et al, 2006). A few examples of tetraamino phosphonium salts exist in the literature (Hart & Sisler, 1964) and some of them are used as catalysis for preparing fluorine-containing compounds by a halogen/fluorine exchange reaction (Schiemenz et al, 2003). Also, the crystal structure of P(NH 2 ) 4 Cl (Horstmann & Schnick, 1996) and [P(NHPh) 4 ]Cl (Bickley et al, 2004) have been reported.…”
