Abstract
Using density-functional theory as implemented in the projector-augmented wave method, we have calculated structures, energy levels, structures of the protonated forms, and proton affinities of the phosphanes PH<sub>3</sub>, PF<sub>3</sub>, P(CF<sub>3</sub>)<sub>3</sub>, PMe<sub>3</sub>, P(NMe<sub>2</sub>)<sub>3</sub>, P(C<sub>6</sub>H<sub>5</sub>)<sub>3</sub>, P(p-C<sub>6</sub>H<sub>4</sub>OMe)<sub>3</sub>, and P(p-C<sub>6</sub>H<sub>4</sub>NMe<sub>2</sub>)<sub>3</sub>. The donor strengths of the phosphanes are discussed in terms of lone-pair energies and proton affinities. The influence of the donor ability of the phosphane ligands on the protonolytic cleavage of the metal–carbon bond in [NiCl(CH<sub>2</sub>CH<sub>2</sub>NH<sub>3</sub>)(PR<sub>3</sub>)<sub>2</sub>]+ complexes has been studied. A linear relationship between the lone-pair energies of the phosphanes and the activation barrier has been established.
