Abstract
![]()
The use of the bis(1-piperidinyl)-substituted carbodiphosphorane
(Ph2(Pip)P)2C (1) as an NCN ligand for the
stabilization of phosphorus cations was studied. A simple ligand for halide exchange
allowed the synthesis and isolation of a series of phosphorus monocations of the type
[1-PR2]+ (with R = Cl, Br, I, CyCl, Ph). These
cations exhibit characteristic NMR and structural properties which nicely correlate with
the charge at the central phosphorus atom and the interaction between the ligand and the
PR2 moiety. Halide abstraction from the monocations does not result in
isolable dicationic compounds but in an unexpected intramolecular
Csp3–H activation in the piperidinyl group. DFT studies
show that the selective activation of the CH2 group next to the nitrogen atom
instead of a CH group at the phenyl substituents proceeds via an iminium intermediate
formed by hydride transfer from the carbon atom to the cationic phosphorus center. This
observation clearly demonstrates the pronounced π acidity of the dicationic
phosphorus species in comparison to compounds with a further π-donor
substituent.

Abstract
This review is dedicated to the chemistry of stable and isolable species that bear two lone pairs at the same C center, i.e., geminal dianions, stabilized by main group elements. Three cases can thus be considered: the geminal-dilithio derivative, for which the two substituents at C are neutral, the yldiide derivatives, for which one substituent is neutral while the other is charged, and finally the geminal bisylides, for which the two substituents are positively charged. In this review, the syntheses and electronic structures of the geminal dianions are presented, followed by the studies dedicated to their reactivity toward organic substrates and finally to their coordination chemistry and applications.
