In this protocol, we apply reductive cobalt catalysis in the allylic defluorinative cross-electrophile coupling reactionbetween 1,1-difluoroalkyl halides and α-trifluoromethyl styrenes. This reaction features broad substrate scope (39 examples), good tolerance of various functionalities, and circumvention of pregenerating organometallics, offering a general synthetic route to prepare diverse organofluorines

with aldehydes and electron-withdrawing-group-activated alkyl bromides, providing straightforward access to various ketones under mild and ligand-free conditions. The photocatalyst TBADT plays a dual role in activating the acyl C–H bond of aldehydes via hydrogen atom transfer and reducing the C–Br bond of alkyl bromides via single-electron transfer. While the terminal C–C bond is forged through polarity-matched
