Infrared Irradiation‐Assisted Pd‐Catalyzed C(sp3)─H Arylation and Tandem Cyclization of Ortho‐Tolualdehydes

Chemistry – A European Journal, EarlyView.
A rapid and efficient protocol for the synthesis of 2‐benzylbenzaldehydes and anthracenes is reported, based on the infrared (IR) irradiation‐assisted Pd‐catalyzed C(sp3)─H arylation and the tandem C(sp3)─H arylation/electrophilic aromatic cyclization of ortho‐tolualdehydes with aryl iodides via a transient directing group (TGD) strategy.

Silver‐Mediated Deuterium Labelling of Quinones and Related Compounds by Hydrogen Isotope Exchange With D2O

Chemistry – A European Journal, EarlyView.
A new silver‐catalyzed H/D exchange reaction was developed for the labelling of quinones and related compounds. Both homogeneous and heterogeneous catalytic processes were implemented using heavy water as a simple deuterium source. The corresponding deuterated compounds were obtained with high isotopic enrichment through a practical method that opens ...

Mechanism of Isonitrilase, a Nonheme Iron Decarboxylase Involved in the Biosynthesis of the Isonitrile Group in Peptides: A Computational Study

Chemistry – A European Journal, EarlyView.
A combination of molecular dynamics and quantum mechanics calculations shows that substrate is tightly bound inside the enzyme structure that enables two successive catalytic cycles with dioxygen and α‐ketoglutarate with an initial desaturation followed by hydrogen abstraction and decarboxylation steps to form an isonitrile substituent.

Remote Migratory Reductive Arylation of Unactivated Alkenes Enabled by Electrochemical Nickel Catalysis

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
we have developed an electrochemical Ni−H catalyzed arylation coupling method of unactivated alkenes with aryl halides. The method displays broad functional group tolerance and proceeds under very mild conditions. Furthermore, aryl chlorides were also compatible substrates in this catalytic system. This conversion holds significant implications for the
