This non-negligible direct P-B interaction, which is related also to the soft nature of the borane frontier orbital, is further supported by substantial spatial overlap between the frontier orbitals on the phosphine/borane fragments and their interaction energy estimations.

The bromide salts [R (3) P x PR'(2)=NSiMe (3)] Br [R' = Me ([6](+)), OCH (2) CF (3) ([8](+)); R (3) P = Me (3) P (a), Et (3) P (b), (n) Bu (3) P (c), dmpm (d, dmpm = dimethylphosphinomethane), dmpe (e, dmpe = dimethylphosphinoethane)] were prepared from the direct reactions between BrMe (2) P=NSiMe (3) (5) and Br (CF (3) CH (2) O)(2) P=NSiMe (3) (7) and the corresponding tertiary phosphines R (3) P or the diphosphines Me (2) P (CH (2))(n) PMe (2) (n = 1, 2).

The X-ray crystal structure analyses revealed close to eclipsed conformations for all members of this series with average dihedral angles theta (C-P-B-C) of 8.1 degrees (8 c), 12.3 degrees (8 b) and 20.3 degrees (8 a).

The reaction of the lithiated phosphine-borane adducts Li [PPhR.BH (3)] or Li [CH (2)-PR (2).BH (3)] with Me (2) NH.BH (2) Cl afforded the hybrid linear species Me (2) NH-BH (2)-PPhR-BH (3) (1, R = Ph; 2, R = H) or Me (2) NH-BH (2)-CH (2)-PR (2)-BH (3) (3, R = Ph; 4, R = Me).
Single-crystal X-ray diffraction studies on 1 and 3, the first for linear hybrid aminoborane/phosphinoborane adducts, confirmed the expected four-coordinate N-B-P-B and N-B-C-P-B frameworks.

Ethynyl- and allenylphosphine-boranes have been prepared by addition at low temperature of borane on the free phosphine.
The photoelectron spectra can be easily described in the case of alpha,beta-unsaturated compounds by the change of the direct conjugation between the lone electron pair and the pi-bond in the free phosphines to hyperconjugation of the sigma (P-B) bond with the unsaturated moiety in the corresponding complexed derivatives.
