Tunable Preparation of β‐Substituted Alkenoate Esters via Radical Alkenylation of C(sp3)–H Bonds with Allenoates

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
Abstract A photocatalytic strategy for the radical alkenylation of aliphatic C(sp3)–H bonds with 2,3‐allenoate esters is described. The protocol takes place upon irradiation of the reaction mixture in the presence of the decatungstate anion, which triggers C−H cleavage in the chosen aliphatic substrates.

Revisiting the Resource Curse in the Age of Energy Transition: Cobalt Reserves and Conflict in Africa [PDF]

open access: yesarXiv
This study reevaluates the traditional understanding of the "political resource curse" by examining the unique impact of energy transition metals, specifically cobalt, on local-level conflicts in Africa. Contrary to previous studies that primarily focus on high-value minerals and their political outcomes resulted from substantial economic revenues ...

Development of Photo‐Biocatalytic Redox System for Asymmetric Synthesis of Optically Active Amines Using Blue Light and Transaminases. A Case Study Toward Mavacamten

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
Abstract α‐Chiral amines are versatile building blocks for the asymmetric synthesis of optically pure high‐added‐value chemicals, including pharmaceuticals, agrochemicals, and natural products. Herein, we report a one‐pot, two‐step sequential deracemization of racemic sec‐alcohols to optically enriched primary amines throught a photo‐biocatalytic ...
