Cu-catalyzed three-component coupling of imines with benzoyl chloride and terminal arylalkynes followed by enyne ring-closing metathesis (RCM) and Heck cyclization afforded medicinally relevant benzoindolines, cyclopropane-fused indenopyridines, pyrroloquinolines, or 1,7-tetrahydrophenanthrolines via divergent cyclization pathways. Unexpectedly, the Pd-catalyzed cyclization of heterocyclic dienes

Tetrahydrofurans and pyrrolidines are among the most important heterocycles found in bioactive compounds. Cyclization-functionalization domino reactions of alcohols or amines onto olefins constitute one of the most efficient methods to access them. In this context, oxy- and aminoalkynylation are especially
A one-pot two-step synthesis of versatile indenones has been developed. This palladium(II)-catalyzed transformation involves generation and condensation of ortho-functionalized 1,2-benzils from 2-(2-arylethynylphenyl)acetonitriles using Ph2SO as the oxidant. The resulting 3-cyanoindenones can be converted to various valuable molecules.

Controlling the shape or morphology of metal nanocrystals is central to the realization of their many applications in catalysis, plasmonics, and electronics. In one of the approaches, the metal nanocrystals are grown from seeds of certain crystallinity through the addition

In order to form flexible printed circuits through inkjet printing technique, the Pd(ll) catalyst ink was printed on the surface of polyimide film modified with KOH solution and then reduced with NaBH4 solution to extract the Pd(O) catalyst nuclei. The
