Chemists Program Alkenes With Switchable Radical and Organometallic Sorting
12+ hour, 15+ min ago (623+ words) Chemists at Wuhan University have unveiled a nickel-catalysed reaction that can build an impressive range of alkene architectures from the same simple set of starting materials, simply by changing the ligand on the catalyst....
Chemists break cycloaddition ‘rule-of-five’ by simply tweaking electronic properties of molecule
4+ day, 1+ hour ago (366+ words) Source: © Ze-Xin Zhang et al, Nature Chemistry, 2026 Switching between an electron-donating group and a withdrawing one can alter the outcome of a radical cyclisation reaction – and confound the ‘rule-of-five’ that dictates that such reactions favour five-membered rings Aggarwal notes that…...
Direct α-Heteroarylation Achieved Sans Transition Metals
2+ week, 1+ day ago (161+ words) Highlights of this article: 1. Extremely simple reaction conditions: Say goodbye to expensive catalysts and demanding ligands. Simply add zinc powder at room temperature to trigger the reaction, and there is no need to prepare Reformatsky reagent in advance ("one-pot" mixing…...

2+ week, 1+ day ago (161+ words) Highlights of this article: 1. Extremely simple reaction conditions: Say goodbye to expensive catalysts and demanding ligands. Simply add zinc powder at room temperature to trigger the reaction, and there is no need to prepare Reformatsky reagent in advance ("one-pot" mixing…...
From amines to nitriles via C–N bond cleavage - Nature Catalysis
2+ week, 6+ day ago (226+ words) Nature Catalysis (2026) Cite this article C–N bond functionalization of aliphatic primary amines is severely hampered by the poor nucleofugality of the NH2 group. Now, a direct catalytic deaminative cyanation of aliphatic primary amines has been established to enable efficient nitrile synthesis,…...
Asymmetric reduction of internal alkenes catalyzed by nickel carbene and Heck coupling reactions
3+ week, 2+ day ago (1048+ words) A collaborative research team led by Shi-Liang Shi at the Shanghai Institute of Organic Chemistry, Chinese Academy of Sciences, and Ming Joo Koh's group at the National University of Singapore, reported an enantioselective reduction of Heck and Heck coupling reactions…...
