1. Synthesis and reduction of [(C 5 H 4 SiMe 3 ) 2 Ln(μ-OR)] 2 (Ln = La, Ce) complexes: structural effects of bridging alkoxides

   https://doi.org/10.1039/D4DT02137A  

   Brown, Adrian N ; Kelleher, Jack N ; Brown, Alexander M ; Saghy, Peter ; Bohl, Joshua J ; Robinson, Jerome R ; Huh, Daniel N ( January 2024 , Dalton Transactions)

   Alcoholysis of (C₅H₄SiMe)₃Ln results in bimetallic complexes with unexpected decreases in Ln⋯Ln distances as bridging alkoxides become bulkier. These complexes were characterized by DOSY NMR, CV, DPV, and a La^IIspecies was observed by EPR.

2. Hydrogenation reactions catalyzed by HN(CH 2 CH 2 PR 2 ) 2 -ligated copper complexes

   HN(CH 2 CH 2 PR 2 ) 2 -ligated copper borohydride complexes, ( R PN H P)Cu(BH 4 ) (R = i Pr, Cy, t Bu), which can be prepared from ( R PN H P)CuBr and NaBH 4 , are capable of catalyzing the hydrogenation of aldehydes in an alcoholic solvent. More active hydrogenation catalysts are ( R PN H P)CuBr mixed with KO t Bu, allowing various aldehydes and ketones to be efficiently reduced to alcohols except those bearing a nitro, N -unprotected pyrrole, pyridine, or an ester group, or those prone to aldol condensation ( e.g. , 1-heptanal). Modifying the catalyst structure by replacing the NH group in ( i Pr PN H P)CuBr with an NMe group results in an inferior catalyst but preserves some catalytic activity. The hexanuclear copper hydride cluster, ( i Pr PN H P) 3 Cu 6 H 6 , is also competent in catalyzing the hydrogenation of aldehydes such as benzaldehyde and N -methyl-2-pyrrolecarboxaldehyde, albeit accompanied by decomposition pathways. The catalytic performance can be enhanced through the addition of a strong base or i Pr PN H P. The three catalytic systems likely share the same catalytically active species, which is proposed to be a mononuclear copper hydride ( R PN H P)CuH with the NH group bound to copper.

3. From Ln 2 O 2 S to Ln 10 OS 14 : exploring the sulphur spectrum of trivalent lanthanoid oxysulphides

   https://doi.org/10.1039/D4DT00294F  

   Wuille_Bille, Brian A ; Velázquez, Jesús M ( April 2024 , Dalton Transactions)

   Lanthanoid oxysulphides exhibit great versatility in their chemical compositions which allow for their optoelectronic properties to be tuned by the relative amounts of oxygen and sulphur present in their crystal structures.

5. A nonsolvolytic fluorine/LiNO 3 -containing electrolyte for stabilizing dynamic interfaces in Li||LiMn 2 O 4 batteries

   https://doi.org/10.1039/D3RA08016A  

   Tang, Tian ; Utomo, Nyalaliska W ; Zheng, J_X Kent ; Archer, Lynden A ( May 2024 , RSC Advances)

   Complementary characterization results show that chemical dissolution of transition metal in LiMn₂O₄is caused by solvolysis-generated HF, which can be suppresed by rational design of a group of nonsolvolytic electrolytes.
