Tin-based FLPs catalyze reductive coupling reactions of amines with CO2 and H2. Water produced by the reaction is well tolerated and TONs up to 300 can be achieved.

Cationic Lewis acids (LAs) are gaining interest as targets for frustrated Lewis pair (FLP)-mediated catalysis. Unlike neutral boranes, which are the most prevalent LAs for FLP hydrogenations, the Lewis acidity of cations can be tuned through modulati

‘Frustrated Lewis pairs’ (FLPs) continue to exhibit unique reactivity for the reduction of organic substrates, yet to date the catalytic hydrogenation of an ester functionality has not been demonstrated. Here we report that iPr3SnNTf2 (1-NTf2; Tf

The catalytic conversion of N2 to N(SiMe3)3 by homogenous transition metal compounds is a rapidly developing field, yet few mechanistic details have been experimentally elucidated for 3d element catalysts. Herein we show that Fe(PP)2(N2) (PP = R2PCH2

We herein explore whether tris(aryl)borane Lewis acids are capable of cleaving H2 outside of the usual Lewis acid/base chemistry described by the concept of “frustrated Lewis pairs” (FLPs). Instead of a Lewis base we use a chemical reductant to g

[Cp*Fe(Me2PCH2CH2PMe2)(CO)]+ [BArF24]− has been synthesised and characterised using single crystal X-ray diffraction, NMR and IR spectroscopies. Reduction of the CO ligand using Na[Et3BH] produces the corresponding neutral formyl complex Cp*Fe(Me2P

A range of amines catalyse the oxidative addition (OA) of H2 to [(Me3Si)2CH]2Sn (1), forming [(Me3Si)2CH]2SnH2 (2). Experimental and computational studies point to ‘frustrated Lewis pair’ mechanisms in which 1 acts as a Lewis acid and involve unu
