Conventional methods carrying out C(sp2)−C(sp2) bondformations are typically mediated by transition‐metal‐based catalysts. Herein, we conceptualize a complementary avenue to access such bonds by exploiting the potential of electrochemistry in combination with organoboron chemistry. We demonstrate a transition metal catalyst‐free electrocoupling between (hetero)aryls and alkenes through readily available

The present invention relates to a novel process for preparing substituted and unsubstituted (2,4-dimethylbiphenyl-3-yl)acetic acids and their esters of the formula (I) using homogeneous and heterogeneous palladium catalysts, and also the intermediates 4-tert-butyl-2,6-dimethylphenylacetic acid and 4-tert-butyl-2,6-dimethylmandelic acid, and to processes for their preparation.
