Angewandte Chemie International Edition, Accepted Article.A cationic Ir(I)‐complex modified with the chiral diphosphine DM‐SEGPHOS mediates the hydroalkylation of diverse α‐methyl styrenes with N‐aryl glycine derivatives. The processes occur with complete branched selectivity and high enantioselectivity. Styrenes possessing higher α‐alkyl substituents also participate to provide the targets with moderate to ...

Development of an Organoautocatalyzed Double σ‐Bond C(sp2)‐N Transamination Metathesis Reaction
Angewandte Chemie International Edition, Accepted Article.The transamination reaction, which involves the conversion of one amine to another, traditionally relies on biological enzyme catalysts. Although chemists have recently developed a few transition metal‐catalyzed methods, mimicking these enzymes to interconvert amine groups in acyclic substrates via transamination metathesis of a single C(sp2)–N bond ...

Nano-Scale Manipulation of Single-Molecule Conformational Transition Through Vibrational Excitation [PDF]
arXivOn-demand control of molecular actions is essential for realizing single-molecule functional devices. Such a control can be achieved by manipulating interactions between individual molecules and their nanoscale environment. In this study, we manipulate the conformational transition of a single pyrrolidine molecule on a Cu(100) surface by exciting its ...

Operating a Multi-Level Molecular Dimer Switch through Precise Tip-Molecule Control [PDF]
arXivControlling structural transitions between molecular configurations is crucial for advancing functional molecular electronics. While reversible switching of bistable two-state molecules has been achieved, creating molecular systems that can be controllably switched between multiple configurations often requires complex synthetic methods, presenting a ...

Angewandte Chemie International Edition, Accepted Article.Sulfonyl fluorides have gained significant importance due to their classification as a click reaction and therefore have seen increased use in drug discovery and biochemistry. Their use, however, is complicated by the methods by which they are synthesized and their general synthetic instability.
