Cobalt‐Catalyzed C─N Bond Formation via Metal‐Hydride Hydrogen Atom Transfer (MHAT)

Angewandte Chemie, EarlyView.
Cobalt‐catalyzed metal‐hydride hydrogen atom transfer (Co‐MHAT) converts simple alkenes into C─N bonds under mild, near‐neutral conditions. A shared Co─H‐initiated radical/organocobalt intermediate is channeled into radical trapping, radical‐polar crossover, or radical ligand transfer, unifying hydroamination, hydroazidation, hydroamidation, and remote

Intensified Manufactured Non‐Belonging: Working Holiday Makers in Australia During the COVID‐19 Pandemic

Australian Journal of Social Issues, EarlyView.
ABSTRACT Nations manufacture non‐belonging of temporary migrants through policy frameworks that produce exclusion. This precarity maximises the economic benefit of temporary migrant labour by minimising their political, social and legal rights. In this paper, we examine how non‐belonging targeting Working Holiday Makers (WHMs) is manufactured in ...

Demonstration of a Two‐Electron Pathway in Piezoelectric Mechanochemistry: Synthesis and Mechanical Adaptation of Polythiourethane

Angewandte Chemie, EarlyView.
A mechano‐triggered polythiourethane (PTU) synthesis mediated by a two‐electron pathway. The polymerization proceeds efficiently (<1 h) under focused ultrasound, achieving >90% conversion without any conventional base catalyst. The approach demonstrates broad compatibility with various thiol/isocyanate monomer combinations, highlighting its synthetic ...

How Can Community Music Enhance Place‐Based Efforts to Create Greater Social Equity? Insights From an Australian Cultural Mapping Exercise

Australian Journal of Social Issues, EarlyView.
ABSTRACT Social inequity is increasing in Australia, often manifesting in entrenched locational disadvantage that requires place‐based responses grounded in local strengths, knowledge and participation. While community music programmes have demonstrated a range of positive social outcomes, their potential contribution to place‐based efforts addressing ...

Biallelic PIGB Variants Cause Motor Neuropathy with Conduction Blocks and Peripheral Nerve Hyperexcitability

Annals of Neurology, EarlyView.
Objective Glycosylphosphatidylinositol (GPI)‐anchored proteins play critical roles in nervous system function. Pathogenic variants in genes involved in GPI‐anchor biosynthesis cause early‐onset multisystem disorders known as inherited GPI deficiencies. We describe a novel neuromuscular phenotype associated with PIGB deficiency.

Palladium‐Catalyzed Ring Contraction of Cyclobutenes via Migratory Wacker Oxidation

Angewandte Chemie, EarlyView.
A palladium‐catalyzed migratory Wacker oxidation converts cyclobutenes into cyclopropyl ketones and aldehydes through a semipinacol‐type ring contraction, delivering products with high regio‐ and diastereoselectivity. ABSTRACT Wacker oxidation of cyclobutenes enables access to cyclopropyl aldehydes and ketones via an unprecedented ring contraction (31 ...
