Reaction between Indazole and Pd-Bound Isocyanides—A Theoretical Mechanistic Study

Molecules, 2018
The mechanism of the addition of indazole (Ind)—a bifunctional aromatic N,NH-nucleophile—to cyclohexyl isocyanide coordinated to the palladium(II) center in the model complex cis-[PdCl2(CNMe)(CNCy)] (1) to give the corresponding aminocarbene ...

Multiple Isocyanide insertions promoted by protic and Lewis acids

Tetrahedron Chem
The protonation, or Lewis Acid complexation, of electrophiles can trigger the sequential insertion of two or more isocyanides resulting in valuable iminonitriles or heterocycles.

Divergent alkynylative difunctionalization of amide bonds through C–O deoxygenation versus C–N deamination

Nature Communications
The transformation and utilization of amides are significant in organic synthesis and drug discovery. Here we demonstrate a divergent alkynylative difunctionalization of amides in a single transformation.
