Isolable Phosphanylidene Phosphorane with a Sterically Accessible Two-Coordinate Phosphorus Atom

Brian A. Surgenor, Michael Bühl, Alexandra M. Z. Slawin, J. Derek Woollins, Petr Kilian*

Angew. Chem. Int. Ed. 2012, 51, 10150 –10153 (communication)

Phosphanylidene phosphoranes are phosphorus analogues of familiarly known Wittig reagent. Only very few examples that are isolable (“bottleable”) are known. We report the first example of phosphanylidene phosphorane stabilized by a rigid peri-substituted backbone. The special peri-geometry results in the two co-ordinate phosphorus atom being sterically unshielded (“naked”), yet the compound is stable up to temperature of ca 100°C.

Reaction with Pd⁰ complex reveals that our compound acts as a source of phosphinidene (RP) moiety, the chemistry of which attracts much current attention as phosphorus analogue of carbene.

1,2-Diphosphaacenaphthene 1,2-Dications: Synthetic, Stereochemical and Computational Study of the Stabilising Role of Naphthalene-1,8-diyl Backbone

D. M. Upulani K. Somisara, Michael Bühl, Tomas Lebl, Neville V. Richardson, Alexandra M. Z. Slawin, J. Derek Woollins and Petr Kilian*

Chem. Eur. J., 2011, 17, 2666 – 2677 (full paper)

1,2-Dications (compounds with two positive charges on adjacent atoms) are still considered as chemical curiosities. We report synthesis and full characterisation (incl. single crystal X-ray diffraction) of two diastereomeric forms of 1,2-diphosphonium, a phosphorus 1,2-dication containing peri-substituted naphthalene motif. The reported compounds are the first examples of chiral 1,2-diphosphoniums. We have shown that their stereochemistry can be manipulated by the choice of (coordinating) anion, and that the epimerisation is accelerated in the presence of fluoride anion. Computational studies highlight the significant contribution of the naphthalene ring in stabilising the 1,2-diphosphoniums with respect to related (non-rigid) C₃-aliphatic backbone.

Assessment of the energy cost of the steric clash of a variety of groups attached to the peri-positions of the naphthalene backbone is included in the paper. This allows making predictions which per-substituted species are unlikely to be synthesised by standard P-C coupling reactions.

Phosphorus Peri-Bridged Acenaphthenes: Efficient Syntheses, Characterisation and Quaternization Reactions

Piotr Wawrzyniak, Alexandra M. Z. Slawin, Amy L. Fuller, J. Derek Woollins and Petr Kilian*

Dalton Trans., 2009, 7883-7884 (communication)

Only very few phosphorus (single-atom) peri-bridged naphthalenes (and acenaphthenes) are known. In this paper, we describe a new synthetic pathway to these intriguing compounds, and report several crystal structures. These peri-bridged species contain four-membered heterocycle C₃P in which all three carbon atoms are part of the aromatic system (i.e. they are sp² hybridised). The sp² hybridisation is normally synonymous with approximately 120 degrees bond angles. In our species these angles are much distorted, to less than 90 degrees. This angular strain results in significant reactivity of these species, with propensity to ring expansion and ring opening reactions.

Intramolecular Phosphine-Phosphine Donor-Acceptor Complexes

Piotr Wawrzyniak, Amy L. Fuller, Alexandra M. Z. Slawin and Petr Kilian*

Inorg. Chem., 2009, 48, 2500-2506 (full paper).

Phosphines (PR₃) are considered prototypical donors because of the presence of the lone pair which is readily accepted by a range of transition metals as well as many main group Lewis acids. Although much less common, molecules in which phosphine acts as an acceptor do exist.

Compounds containing a combination of phosphine donor – phosphine acceptor are usually highly unstable and decompose well below room temperature. The main achievement described in this paper is the preparation of a room temperature stable intramolecular complex, in which two different phosphine functionalities (ArPiPr₂ and ArPCl₂) act as a donor and as an acceptor, respectively. The fixed peri-region geometry appears to contribute to stabilization of this unusual bonding situation.

1,8,9-Substituted Anthracenes, Intramolecular Phosphine Donor Stabilized Metaphosphonate and Phosphenium

Petr Kilian* and Alexandra M. Z. Slawin

Dalton Trans., 2007, 3289-3296 (full paper).

A series of 1,8,9-tris(phosphorus) substituted anthracenes was synthesised and fully characterised. The substitution pattern in these molecules is a good template for introducing unusual P→P interactions. Starting from highly crowded bis(amino) phosphine (pictured below), metaphosphonato (single phosphine donor stabilised) as well as phosphenium (doubly phosphine donor stabilised) environments were synthesised.
