Room-Temperature Stille Coupling of Tetraarylstannanes via Palladium-Catalyzed C-H Activation
摘要:
An effective room-temperature Stille cross-coupling of aryl ureas with tetraarylstannanes via palladium-catalyzed C-H bond activation is reported, providing a mild method for direct arylation of aromatic C-H bonds.

Exogenous photocatalyst-free, single nickel-catalyzed carbon–heteroatomcoupling under visible-light irradiation is reported. Over 15 classes of nucleophile can efficiently couple with aryl/alkene halides to afford valuable heteroatomic arenes/alkenes. The unprecedentedly broad substrate scope and late-stage modification of valuable molecules fully demonstrate the benefits of the method.
