A process for the production of acylbenzenes, comprising reacting diacetoxybenzoyl chloride with a Grignard reagent in the presence of an iron-containing catalyst. The acylbenzenes are useful intermediates in a multistep process for the preparation of resveratrol.

The first enantioselectiveradical trifluoromethylation of benzylicC–Hbonds has been established by a cooperative photoredox and copper catalysis system, providing straightforward access to structurally diverse benzylic trifluoromethylation products in good yields with excellent enantioselectivities under mild conditions. Our method features a broad substrate scope and excellent functional group
