acyl substituent across an alkene, oxyacylation of alkenes, using rhodium catalyzed C–O bond activation of an 8-quinolinyl ester is described. Our unsuccessful attempts at intramolecular carboacylation of ketones via C–C bond activation ultimately informed our choice to pursue and develop the intramolecular oxyacylation of alkenes via quinoline-directed C–O bond activation. We provide a full account

We describe herein a palladium‐catalyzed tandem oxidative arylation/olefination reaction of aromatic tethered alkenes/alkynes for the synthesis of dihydrobenzofurans and 2 H‐chromene derivatives. This reaction features a 1,2‐difunctionalization of C−C π‐bond with two C−H bonds using O2 as terminal oxidant at room temperature. The products obtained are valuable synthons and important scaffolds in biological

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.
