TL;DR: The synthesis and reactivity of a chiral aminoborane displaying both rapid and reversible H2 activation and the catalyst shows exceptional reactivity in asymmetric hydrogenation of enamines and unhindered imines with stereoselectivities of up to 99% ee.

TL;DR: It is demonstrated that simple 2-aminopyridinium salts efficiently catalyze the C-H borylation of hetarenes with catecholborane and that this reaction is presumably mediated by a borenium species isoelectronic to2-aminophenylboranes.

TL;DR: Topological analysis of transition states points to the structural invariance of certain fragments of the transition state, such as the protonated catalyst and the anionic fragment of approaching reactants, that contribute to the formation of the major stereoisomeric products.

TL;DR: The thermodynamic and kinetic features as well as the mechanism of this reaction are studied by variable-temperature NMR spectroscopy, spin-saturation transfer experiments, and DFT calculations, which provide comprehensive insight into the nature of 1.

TL;DR: The development of a boron/nitrogen-centered frustrated Lewis pair (FLP) with remarkably high water tolerance is presented, and this metal-free catalytic variant displays a notably broad chemoselectivity and generality.
