Treatment of benzotrifluorides with sodium dispersion in the presence of bis(pinacolato)diboron leads to diborative reduction to obtain diborylbenzylsodium species. These anionic species not only react with reactive organic halides, but also with aromatic carbonyl compounds to produce alkenylboron compounds via Peterson-type olefination. The key to the success of generating diborylbenzylsodium species lies in the immediate capture of unstable difluorobenzylsodium with co-existing reduction-resistant bis(pinacolato)diboron.

The success of the generation of the diborylbenzylsodium species lies in immediate capture of initially formed unstable difluorobenzylsodium with co-existing reduction-resistant bis(pinacolato)diboron.
