N-Heterocyclic carbenes (NHCs) are nowadays ubiquitous and indispensable as ancillary
ligands in organotransition metal chemistry, with an enormous variety of NHC types known …

The coexistence of a strong Lewis acid and a Lewis base in solution, the so called frustrated
Lewis pair, has led to the discovery of metal-free hydrogen activation. Since then, this …

The metal‐free activation of hydrogen by frustrated Lewis pairs (FLPs) is a valuable method
for the hydrogenation of polarized unsaturated molecules ranging from imines, enamines …

Two alternative qualitative reactivity models have recently been proposed to interpret the
facile heterolytic cleavage of H2 by frustrated Lewis pairs (FLPs). Both models assume that …

Classical and frustrated Lewis pairs (LPs) of the strong Lewis acid (LA) Al (C6F5) 3 with
several Lewis base (LB) classes have been found to exhibit exceptional activity in the Lewis …

The hydrosilylation reaction of a carbonyl group catalyzed by tris (pentafluorophenyl)
borane, B (C6F5) 3, is investigated by using the DFT method. M06-2X level calculations …

Frustrated carbene-borane Lewis pairs, such as 1/B (C6F5) 3, that are prevented from
normal adduct formation by steric factors [1] were recently shown to exhibit a very strong …

The intramolecular cyclohexylene-bridged P/B frustrated Lewis pair [Mes2P C6H10 B
(C6F5) 2] 1b reacts rapidly with NO to give the persistent FLP-NO aminoxyl radical 2b …
