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.
