Nickel‐Catalyzed Three‐Component Coupling Reactions of Iodobenzenes, an Isocyanide, and a Disilathiane: Access to Cyclic Thioimidates and Secondary Thioamides

European Journal of Organic Chemistry, EarlyView.
The one‐pot synthesis of 3‐benzylidenbenzo[c]thiophen‐1‐amines was achieved through the nickel‐catalyzed three‐component coupling reaction of 1‐ethynyl‐2‐iodobenzenes, tert‐butyl isocyanide, and hexamethyldisilathiane. This procedure is applicable to the preparation of secondary thioamides using aryl iodides.

Phase‐Transfer‐Catalyzed Interrupted Barton–Zard Reaction Between Electron‐Deficient Indoles and Benzophenone‐Derived Isocyanides

European Journal of Organic Chemistry, EarlyView.
A cascade reaction under phase‐transfer conditions between 3‐nitro indoles and isocyanomethylene dibenzenes affords the construction of pyrrolo[3,4‐b]indole cores. Control experiments provide insight into moderate product yields and clarify why the reaction is not amenable to asymmetric induction. A cascade reaction enabling the construction of pyrrolo[

Design, Synthesis, and Photophysical Studies of Functionalized Polyaromatic Isonitriles as Visible Light Photoredox Catalysts

European Journal of Organic Chemistry, EarlyView.
A new series of structurally rich polyaromatic isonitriles is presented as photoredox catalysts. Their photophysical properties are investigated by UV–Vis absorption and fluorescence measurements, combined with experimental and theoretical studies to evaluate both ground‐ and excited‐state redox properties.

A trustworthy mechanochemical route to isocyanides

Beilstein Journal of Organic Chemistry, 2022
Isocyanides are hardly produced, dramatically sensitive to purification processes, and complex to handle as synthetic tools. Notwithstanding, they represent one of the most refined and valuable compounds for accessing sophisticated and elegant synthetic ...

Base Metal Catalyzed Isocyanide Insertions [PDF]

Angewandte Chemie, 2019
AbstractIsocyanides are diverse C1 building blocks considering their potential to react with nucleophiles, electrophiles, and radicals. Therefore, perhaps not surprisingly, isocyanides are highly valuable as inputs for multicomponent reactions (MCRs) and other one‐pot cascade processes.

Poly(O‐Propargyl‐N‐Amino Carbamate), a Reactive Polymer to Underpin Biomedical Applications of Poly(acetylene)s

Macromolecular Rapid Communications, EarlyView.
We report here a new methodology to prepare functional poly(acetylene)s under aqueous conditions. This methodology is underpinned by poly(O‐propargyl‐N‐amino carbamate) (P1), a reactive poly(acetylene) carrying acyl hydrazines. Thus, P1 reacts with aldehydes to give functional poly(acetylene)s, including cationic, hydrophobic, and sugar‐loaded poly ...
