Selective Formation of a 1,2‐Diborane(4) and Alcohol‐Driven B─B Bond Cleavage to Generate H2
Chemistry – A European Journal, EarlyView.Diborane(4) chemistry reveals unusual reactivity of electron‐deficient p‐block compounds. Reaction of B2Cat2 (Cat = benzene‐1,2‐diolate) with mesityllithium (MesLi; Mes = 2,4,6‐trimethylphenyl) gives a rare 1,2‐diborane(4) featuring a catecholate ligand. Alcoholysis cleaves the B─B bond and ultimately generates H2.

ChemSusChem, Volume 18, Issue 6, March 15, 2025.The addition of Na2CO3 or K2CO3 to sewage sludge prior to combustion leads to the production of ashes containing phosphate in the form of buchwaldite‐like phases (Ca(Na/K)PO4). Compared to conventional sewage sludge mono‐ashes, such Na‐ or K‐ashes show greatly increased P‐solubilities and proved to be potent P‐fertiliser materials in greenhouse ...

ChemSusChem, Volume 18, Issue 6, March 15, 2025.we have developed an electrochemical Ni−H catalyzed arylation coupling method of unactivated alkenes with aryl halides. The method displays broad functional group tolerance and proceeds under very mild conditions. Furthermore, aryl chlorides were also compatible substrates in this catalytic system. This conversion holds significant implications for the

Photocatalyst‐Free Trifluoromethylation of Indolizines Through an Electron Donor–Acceptor Complex
European Journal of Organic Chemistry, EarlyView.A new photocatalyst‐free pathway for the direct C‐3‐trifluoromethylation of indolizines and imidazo[1,2‐a]pyridines through an electron donor–acceptor (EDA) complex is studied. This regioselective reaction supports a wide range of functional groups, indicating good versatility and robustness.
