Article Abstract
We present a luminescent Ir(III) complex featuring a bidentate halogen bond donor site capable of strong anion binding. The tailor-made Ir(III)(L) moiety offers a significantly higher emission quantum yield (8.4 %) compared to previous Ir(III)-based chemo-sensors (2.5 %). The successful binding of chloride, bromide and acetate is demonstrated using emission titrations. These experiments reveal association constants of up to 1.6×10 M. Furthermore, a new approach to evaluate the association constant by utilizing the shift of the emission was used for the first time. The experimentally observed characteristics are supported by quantum chemical simulations.

For over half a century, -halogenated arenes, widely used in cross-coupling reactions, are mainly synthesized and manufactured by stoichiometric-directed -lithiation/halogenation technology. While catalytic C-H halogenation has emerged as a potentially environmentally friendly method, the need for stoichiometric bases, expensive oxidants, and installation of directing groups prevented its adoption in scalable synthesis. In addition, the ligandless Pd(II)-catalyzed C-H halogenation is incompatible with heterocyclic substrates, thus limiting its use in medicinal chemistry substantially.

Nickel photocatalysis has recently become vital to organic synthesis, but how the NiXL pre-catalyst (X = Cl, Br; L = bidentate ligand) becomes activated to NiXL has remained puzzling and is typically addressed on a case-by-case basis. Here, we reveal a general mechanism where light induces photolysis of the Ni-X bond, either via direct excitation or triplet energy transfer. Photolysis produces NiXL and a halogen radical, X.

Chelation-assisted olefinic C-H functionalization has been demonstrated to be a powerful method of constructing multi-substituted alkenes from simpler ones. This strategy produces complex alkenes in a regio- and stereoselective manner, followed by C-H endo- and exo-cyclometallation. Among the various directing groups developed, N,N- and N,O-bidentate directing groups are the most widely used to selectively promote C-H functionalization due to their fine, tunable, and reversible coordination with the metal center.

As the employment of "non-classical" non-covalent interactions like halogen bonding (XB) in asymmetric catalysis is still at a very early stage, there are significant challenges to overcome. In some reported cases, the relevance of halogen bonding to the catalytic action is unclear, while in others, catalyst activity is limited. Herein, we present the second generation of a bidentate iodine(I)-based halogen bond donor as a modifiable and highly active chiral halogen bonding catalyst.

Halogen bonding has been established as a promising tool in organocatalysis. Asymmetric processes are nevertheless scarce, and their applications are limited to a few studies applying chiral halogen bond donors. Herein, we combine halogen bonding with asymmetric counteranion-directed catalysis, providing the first highly enantioselective example of such an approach.
