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.
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.
Recent achievements on the carbonylative synthesis of quinolinone derivatives have been summerized and discussed.
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.
