Alkyl aryl ketones are a class of valuable compounds in chemistry and biology, which are widely used in the pharmaceutical, spice, dye, pesticide, functional materials, and organic synthesis industries. A cobalt-catalyzed oxyalkylation reaction of aryl olefin with tert-butyl hydroperoxide (TBHP) and cyclic ethers was developed. Various substrates with electron-withdrawing or electron-donating groups were tolerated in this protocol to provide the α-alkyl substituted aceto- phenones in moderate yields. The present protocol features broad substrate scope, and flexibility, allowing rapid assembly of a series of value-added acetophenone derivatives under mild conditions with good reaction efficacy.

Key words: alkyl aryl ketone, cobalt-catalysis, oxyalkylation, acetophenone derivative
