new catalyst system able to efficiently perform the synthesis of styrenes via CH bond functionalization and a subtle ligand modification are described. The high level of activity achieved allows for the synthesis of highly functionalized α,β‐substituted styrenes, even the elusive E‐configured trisubstitutedolefins, in a regio‐ and stereoselective manner. Mechanistic experiments allowed for the identification
