A copper-catalysed direct oxidative Csp(3)-H methylenation to terminal olefins using DMF as one carbon source was developed. In this reaction, various functional groups were well tolerated, thus providing a simple way to construct arylvinylketones and arylvinylpyridines. The preliminary mechanistic investigations revealed that CH2 was from DMF (N-CH3).

A strategy for synthesis of β‐aryl‐α‐naphthols has been established through an iron‐promoted domino C(sp 3)−H/C(sp )−H and C(sp 2)−H/C(sp )−H dehydrogenative coupling of deoxybenzoins and alkynes. The synthesis uses inexpensive materials with a broad substrate scope and features simple operations with excellent regioselectivity. This study provides an alternative access to various β‐aryl‐α‐naphthols

A mehtod for the synthesis of terminalolefins by α-methylenation of aromatic ketones is reported. The reaction was carried out in air using acetonitrile as one carbon source and Selectfluor as a mild oxidant. The scope and versatility of the method were demonstrated with 29 examples. A Selectfluor-promoted oxidative reaction mechanism is proposed based on the experimental results.
