Abstract

Abstract A new catalyst system able to efficiently perform the synthesis of styrenes via C [BOND] H 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 trisubstituted olefins, in a regio-and stereoselective manner. Mechanistic experiments allowed for the identification of the corresponding ...
