A NiOx‐Mediated Z‐Scheme Hybrid Photocatalyst for Efficient and Selective Oxidation of Inert C(sp3)–H Bonds

open access: yesChemCatChem, Volume 18, Issue 5, 13 March 2026.
A NiOx‐mediated Z‐scheme NiOx‐BWO‐TiO2 hybrid photocatalyst for the oxidation of inert benzylic C(sp3)─H bonds to aromatic aldehydes using molecular oxygen has been developed. ABSTRACT The selective photocatalytic oxidation of inert benzylic C(sp3)–H bonds to aromatic aldehydes using molecular oxygen remains a formidable challenge due to uncontrolled ...

Sulfur Ylides in Skeletal‐Editing—Ring Expansion Reactions

open access: yesHelvetica Chimica Acta, Volume 109, Issue 3, March 2026.
Sulfur ylides (S‐ylides) are emergent diazo surrogates that enable skeletal editing and ring expansion with safer handling and broad functional group tolerance. This perspective covers pioneer works and highlights recent advances in the field, while outlining key challenges and future directions that may redefine the role of S‐ylides in modern ...

Effect of α‐Hydrazino Acids on the Performance of H‐Pro–Pro‐Xaa Catalysts in the Conjugate Addition of Aldehydes to Nitroolefins

open access: yesChemistrySelect, Volume 11, Issue 11, 18 March 2026.
The tripeptide Pro‐Pro‐D‐hVal‐OMe, which lacks an acidic group, catalysed the conjugate addition of aldehydes to nitroolefins and afforded γ‐nitroaldehydes in 79–97% yield and 88:14–93:7 e.r. The proposed reaction mechanism relies on the active role of hydrazide NHβ or NHα protons in hydrogen bonding with the reacting species.

Naphthalene‐Modified Cationic Initiators for Superior Polymerization Stability and Thermal Conductivity in Epoxy Thermosets

open access: yesSmall Science, Volume 6, Issue 3, March 2026.
Naphthalene‐modified cationic initiators extend epoxy curing time, preserving intrinsic LC ordering and achieving exceptionally high thermal conductivity of 0.86 W m−1 K−1 in unfilled networks. Incorporating thermally conductive fillers further boosts performance, yielding composite conductivities up to ~25 W m−1 K−1.
