Efficient Screening and Library Generation in Parallel C–C Coupling Reactions Mediated by Organosilica SiliaCat Palladium Catalysts
摘要:
Organosilica SiliaCat palladium catalysts applied to the conversion of widely different substrates in Suzuki, Sonogashira, and Heck coupling reactions run in a parallel synthesizer enable quick screening of the reaction system with identification of the best reaction conditions and rapid library generation.

Visible light excitation of iodine(III)–BF3 complex enables the formation of carbocations from C(sp3)–H bonds. The complexes are generated catalytically from iodoarene, carboxylate ligand, the oxidizing agent Selectfluor, and the Lewis acid BF3. This modular catalytic system allows the formation of synthetically valuable amine derivatives without a metal- or photocatalyst.
