Generation and Reactivity of a Ni(μ-1,2-peroxo) Complex.

Published: December 2020

High-valent transition metal-oxo, -peroxo, and -superoxo complexes are crucial intermediates in both biological and synthetic oxidation of organic substrates, water oxidation, and oxygen reduction. While high-valent oxygenated complexes of Mn, Fe, Co, and Cu are increasingly well-known, high-valent oxygenated Ni complexes are comparatively rarer. Herein we report the isolation of such an unusual high-valent species in a thermally unstable Ni(μ-1,2-peroxo) complex, which has been characterized using single-crystal X-ray diffraction and X-ray absorption, NMR, and UV-vis spectroscopies. Reactivity studies show that this complex is stable toward dissociation of oxygen but reacts with simple nucleophiles and electrophiles.

Developing high-performance Ir-based catalysts for selective catalytic reduction of NOx by CO(CO-SCR) under low temperatures remains challenging. This study presents an Ir-based catalyst encapsulated in ZSM-5 (Ir@ZSM-5), with Ir species partially confined in micropores (Irδ+) and partially aggregated on the surface (Ir0), achieving ~88% NOx conversion at 230 °C in the presence of 5% O2 and 100 ppm SO2. The confined Irδ+ species exhibit enhanced stability and oxidized states, while surface-aggregated Ir0 species, with weaker oxygen coordination, remain in a metallic state.

The unique photophysical properties of the lanthanoids provide the core functionality for various high-tech applications including optoelectronic materials, lasers, anti-counterfeiting dyes or tools for biological sciences. Combination of these luminophores with photoswitches has the potential to make them remote controllable and adds new layers of complexity to their applications. We herein report that such a photomodulation of EuIII, TbIII and YbIII luminescence is possible with the aid of diazocine photoswitches.

Herein, we report a hydrogen-bonded supramolecular hybrid composed of a cobaloxime complex and a covalent organic framework (COF) that achieves photocatalytic overall water splitting. The designed COF features ternary units and dual linkages, which induce asymmetric linkers. Upon photoexcitation, this asymmetry facilitates directed electron transfer and spatially separated redox sites, resulting in a long-lived charge-separated state.

The semireduction of alkynes is an indispensable transformation for the synthesis of Z-alkenes. Although extensive studies with mostly transition metal-based catalysts have enabled it to produce a broad scope of alkenes, a Scifinder search and a robustness screen of Lindlar's catalyst indicate that highly Lewis-basic nitrogen and sulfur-containing motifs, which are prevalent in drugs, remain problematic. Herein, we report an alkyne semi-reduction using an organic photoreductant that tolerates all 10 of the most common Lewis-basic motifs in drugs.

An unprecedented strategy for unlocking a new and efficient  functional group transfer protocol has been demonstrated to synthesize a variety of complex organic sulfoxides chemoselectively, starting from organic sulfides. The strategy of this new functional group transfer protocol is based on harnessing the potential of metalloradical-assisted intermolecular functional group transposition or 'InterGroupXfer' to replace highly sensitive and reactive high valent metal intermediates, [M=X] (X = O, NH).This sustainable functional group transfer strategy employs earth abundant iron catalyst and bench-stable and convenient-to-handle hydroxyl amine derived surrogate, operates under mild conditions in water or even under solvent free condition, exhibits broad functional group tolerance, as well as versatility of reaction scale  and proceeds without the use of any precious metal catalyst or additional oxidant.
