摘要: A new catalyst system able to efficiently perform the synthesis of styrenes via C—H bond functionalization and a subtle ligand modification are described. The high level activity achieved allows for highly functionalized α,β-substituted styrenes, even elusive E-configured trisubstituted olefins, in regio- stereoselective manner. Mechanistic experiments allowed identification corresponding synthetic intermediates.
