Abstract

The unsymmetrical diborane(4) pinB-B((RN)(2)(C6H4)) (R = Me, Bn) reacts with [(Me3P)(4)Rh-X] (X = Me, OtBu) giving predominantly either [(Me3P)(4)Rh-Bpin] or [(Me3P)(3)Rh-B((RN)(2)(C6H4))] depending on X. At low temperatures in the presence of excess PMe3 the unprecedented equatorial boryl complex [(Me3P)(4)Rh-B((MeN)(2)(C6H4))] is formed.

Kuldeep Chand, Naorem Jemes Meitei, Yu-Lun Chang, Cheng-Long Tsai, Hsing-Yin Chen, Sodio C. N. Hsu

Summary: An investigation was conducted to study the reactivity of O-2 with unsymmetrical beta-diketiminato copper-(I) complexes using spectroscopic and titration analysis. The length of chelating pyridyl arms played a role in the formation of mono- or di-nuclear copper-dioxygen species at -80 degrees C. The chelating length also influenced the ligand degradation behavior and the Cu/O-2 binding ratio.

Engineering Semiconductor Quantum Dots for Selectivity Switch on High-Performance Heterogeneous Coupling Photosynthesis

Ming-Yu Qi, Marco Conte, Zi-Rong Tang, Yi-Jun Xu

Summary: Semiconductor-based photoredox catalysis offers a sustainable and mild strategy for organic transformation, but controlling selectivity is challenging due to non-selective interactions between semiconductors and photogenerated radicals. By designing atomically dispersed cocatalysts on semiconductor quantum dots, we achieve precise selectivity in high-performance heterogeneous coupling photosynthesis. This work overcomes the difficulties of selectivity regulation in semiconductor-based photochemical synthesis, highlighting the potential of utilizing atomically dispersed cocatalysts to control unselective radical conversion for selective heterogeneous photosynthesis.

Summary: Gold(II) complexes have been less utilized in catalysis compared to their gold(I) and gold(III) counterparts. However, gold(II) complexes offer potential in homo-coupling and cross-coupling reactions, as they are more easily accessible through simplified oxidation and reduction processes. Gold(II) exhibits characteristics of both soft acid gold(I) and hard acid gold(III). This review explores the unique reactivity and potential applications of gold(II) species, highlighting their significance in catalytic transformations.

Aryl selenonium vs. aryl sulfonium counterions in polyoxometalate chemistry: the impact of Se+ cationic centers on the photocatalytic reduction of dichromate

Mahender Singh, Aakash Yadav, Ranjit Singh, Chullikkattil P. Pradeep

Summary: A new aryl selenonium polyoxometalate hybrid was developed and compared with an aryl sulfonium polyoxometalate hybrid in terms of their photocatalytic properties. It was found that the aryl selenonium hybrid exhibited better catalytic performance, which could be attributed to the larger atomic radii of selenium stabilizing the photogenerated electron-hole pair more efficiently. Additionally, the generation of elemental selenium through cleavage of C-Se bonds during catalysis was observed.
