Harnessing redox-inactive rare-earth metals for photocatalytic reductive coupling of benzyl bromides

Green Synthesis and Catalysis (2024)

Zhiqiang Hao Zhongzhen Wang Dajiang Huang Xinlei Huangfu Xuejing Yang

Compared with rare and expensive late-transition metals, rare-earth photocatalysts are much less investigated in synthetic chemistry, particularly concerning redox-inactive rare-earth metals. Herein, we describe a general strategy to realize the redox-inactive rare-earth photocatalysis by grafting a light-absorbing scaffold onto common ligands in rare-earth organometallics. Three guanidinate rare-earth complexes with photocatalytic functions were synthesized and found to exhibit higher catalytic efficiency than phenothiazine in the reductive homocoupling of benzyl bromides. These preliminary results illustrated that our "grafting" strategy could serve as a facile methodology for the construction of redox-inactive rare-earth photocatalysis systems.

Transfer of Aryl Halide to Alkyl Halide: Reductive Elimination of Alkylhalide from Alkylpalladium Halides Containing syn‐β‐Hydrogen Atoms

Angewandte Chemie International Edition (2014)

Wei Hao Junnian Wei Weizhi Geng Wen‐Xiong Zhang Zhenfeng Xi

Abstract β‐Hydride abstraction is a well‐accepted elementary step for catalytic cycles in organometallic chemistry. It is usually anticipated that alkylpalladium halides containing syn‐β‐hydrogen atoms will undergo β‐hydride abstraction to afford the Heck‐type products. However, this study discloses that the above general knowledge is only conditionally correct. Our experimental results demonstrate that the reductive elimination of alkylhalides from alkylpalladium halides containing syn‐β‐hydrogen atoms may surpass the β‐hydride abstraction or even become exclusive in certain cases.

Well-Defined Scandacyclopropenes: Synthesis, Structure, and Reactivity

Journal of the American Chemical Society (2019)

Ze‐Jie Lv Zhe Huang Jinghang Shen Wen‐Xiong Zhang Zhenfeng Xi

Although transition metallacyclopropenes have been extensively explored for more than 40 years, their analogues of rare-earth metals have remained elusive. Herein, we report the synthesis of three isolable scandacyclopropenes, thus representing the first well-defined rare-earth metallacyclopropenes. Structural characterization and DFT calculations revealed a delocalized three-center two-electron (3c-2e) aromatic system. When scandacyclopropenes were treated with phenylacetylene or TMSN3, the scandium complex of bis-phenylacetylide or bis-azide was obtained, respectively. The reaction of scandacyclopropene with phenazine could provide the binuclear ring-opening scandium complex via 1,4-insertion of phenazine into one Sc–C bond and subsequent metathesis reaction. However, insertion of TMSNCO or N2O into one Sc–C bond of scandacyclopropenes gave a five- or six-membered scandacycle. In addition, scandacyclopropenes can serve as a two-electron reductive agent for PhSSPh and PhNNPh. These results show that scandacyclopropenes exhibit diversified and unique reactivity toward small molecules because of the strongly nucleophilic alkenediyl dianion and highly strained three-membered ring.

Frontispiece: Alkenyl Magnesium Compounds: Generation and Synthetic Application

Chemistry - A European Journal (2018)

Miaomiao Zhu Liang Liu Haitao Yu Wen‐Xiong Zhang Zhenfeng Xi

Alkenyl magnesium compounds are frequently used in organic synthesis and they are often proposed as active intermediates in organic synthesis. Currently, there are three main types of alkenyl magnesium compounds, including alkenyl Grignard reagents, alkenyl magnesium carbenoids and magnesacarbocycles containing alkenyl magnesium bonds. In their Minireview on page 19122 ff., W.-X. Zhang, Z. Xi et al. have summarized the preparation, reactivity and application of these three types of alkenyl magnesium compounds.

Synthesis, Structure, and Magnetic Properties of Rare-Earth Bis(diazabutadiene) Diradical Complexes

Inorganic Chemistry (2021)

Haihan Yan Botao Wu Yin‐Shan Meng Wen‐Xiong Zhang Zhenfeng Xi

New kinds of diradical rare-earth metal complexes supported by diazabutadiene (DAD) ligands, [(DAD)2LnN(TMS)2] (1; Ln = Dy, Lu; TMS = SiMe3), were synthesized and studied. They showed a new [radical–Ln–radical] alignment with distorted square-pyramidal geometry. Structural and density functional theory analysis illustrated the radical anionic nature of the ligands. Magnetic studies revealed antiferromagnetic coupling of the two radicals in 1-Lu. 1-Dy showed typical single-molecule-magnet (SMM) behavior with an effective energy barrier of 231 K, which is much higher than those of similar radical-containing SMMs. Magnetostructural analysis suggests that the anionic [N(TMS)2]− group plays a vital role in the SMM property. This study provides a new platform for further improving the performance of radical–Ln SMMs.
