The one-pot synthesis of valuable E-chalcones is achieved using a multifunctional Ru@SiO2-[Pd–NHC] catalytic system combining molecular and nanoparticle sites for efficient carbonylative Sonogashira coupling and selective hydrogenation.
Conjugated porous polymers bearing flavone moieties were synthesized via a tandem carbonylative Sonogashira coupling/cyclization approach, and were proved to be efficient metal-free photocatalysts for the photosynthesis of 2,3-dihydrobenzofurans.
A variety of ketones, amides, and aromatic ynones were synthesized in moderate to good yields in the presence of a heterobimetallic PdCl(PPh3)2SnCl3 catalyst by using chloroform as a CO source in a one-pot fashion.
The selective reduction of titanocene dichloride to either trivalent or divalent titanocene species depending on the lanthanide metal is described and corroborated by reactivity, ESI-MS, EPR and SCXRD studies.
DNA-supported palladium catalysts (Pd/DNA) have been used in imination, hydrogenation, cross-coupling, and carbonylation reactions. In this mini review, the effectiveness of Pd/DNA catalysts and the impact of the DNA support on the reusability of palladium in recent years has been examined.
