Nothing frustrating about “Frustrated Lewis pairs

In the six short years following our initial report, the areas impacted by the chemistry of “frustrated Lewis pairs” (FLPs) continue to grow most dramatically. The collection of papers presented in this issue of Dalton Transactions reflect the broadening impact and excitement of the new field of FLP chemistry.

Hydrogen activation by 2-boryl-N,N-dialkylanilines: a revision of Piers’ ansa-aminoborane

Two 2-[bis(pentafluorophenyl)boryl]-N,N-dialkylanilines, exemplifying a new class of intramolecular frustrated B/N Lewis pairs, can activate hydrogen at near ambient conditions; besides, one of them can hydrogenate imines and enamines in a catalytic fashion.

Asymmetric hydrogenation of imines with a recyclable chiral frustrated Lewis pair catalyst

A camphor based chiral phosphonium hydrido borate zwitterion was synthesised and successfully applied in the enantioselective hydrogenation of imines with selectivities up to 76% ee. The high stability of the novel chiral FLP-system enables effective recycling of the metal-free catalyst.

Novel H2 activation by a tris[3,5-bis(trifluoromethyl)phenyl]borane frustrated Lewis pair

Tris[3,5-bis(trifluoromethyl)phenyl]borane (BArF18) forms a Frustrated Lewis pair with 2,2,6,6-tetramethylpiperidine, which cleaves H2 to provide the novel bridging borohydride [μ-H(BArF18)2].

Association of frustrated phosphine–borane pairs in toluene: molecular dynamics simulations

Explicit solvent molecular dynamics simulations of the (tBu)3P/B(C6F5)3 pair in toluene allowed the estimation of the degree of intermolecular association and the population of encounter complex states in solution phase.

Intramolecular Lewis acid–base pairs based on 4-ethynyl-2,6-lutidine

The reaction of 4-ethynyl-2,6-lutidine, (2,6-Me2)(4-HC[triple bond, length as m-dash]C)C5H2N, with the Lewis acid B(C6F5)3 leads to the zwitterion [(2,6-Me2)(4-(C6F5)3BC[triple bond, length as m-dash]C)-C5H2NH], whereas its reactions with MR3 (M = Al, Ga, In; R = Me, Et) lead exclusively to metallation of the ethynyl group and the products [(2,6-Me2)(R2MC[triple bond, length as m-dash]C)C5H2N].

Fixation of carbon dioxide and related small molecules by a bifunctional frustrated pyrazolylborane Lewis pair

The fixation of carbon dioxide and related small molecules is efficiently accomplished by a bifunctional frustrated pyrazolylborane Lewis pair; CO2 fixation presumably proceeds via a van der Waals complex with a low energy barrier of approximately 7.2 kcal mol−1.
