Electrochemical N‐hydroxyphthalimide Catalyzed Addition of α‐Alkoxy Radicals to Oxime Ethers

open access: yesAdvanced Synthesis &Catalysis, Volume 368, Issue 4, 17 February 2026.
N‐hydroxyphthalimide (NHPI) serves as an electrocatalyst that enables selective hydrogen atom transfer from alkyl alcohols under mild electrochemical conditions. In contrast with the well‐known electrochemical oxidation to their corresponding aldehydes or ketones, α‐alkoxy radicals were successfully coupled with oximes promoting a carbon‐carbon bond ...

Presupernova evolution and explosive nucleosynthesis of zero metal massive stars

open access: yes, 2012
We present a new set of zero metallicity models in the range 13-80 $\rm M_\odot$ together to the associated explosive nucleosynthesis. These models are fully homogeneous with the solar metallicity set we published in Limongi & Chieffi (2006) and will be ...

Exploring Ligand Effects in the Selective Catalytic Dehydrogenative Borylation of Alkynes with Aluminum

open access: yesAdvanced Synthesis &Catalysis, Volume 368, Issue 1, January 2026.
Proper selection of a modified guanidinato ligand allows for the selective catalytic dehydroborylation of terminal alkynes by an air‐stable aluminum complex. A plausible reaction pathway is suggested based on DFT studies, where the auxiliary substituent of the guanidinato ligand actively participates in the activation of the σ CH bond.
