EOCAS Electrophile Olefin Combination

The hydroarylation of olefins is relatively uncommon in photochemistry, despite a high interest in this process which allows the formation of an aryl-carbon bond via the direct activation of an aromatic, with no need for leaving groups in both components of the reaction. The process follows a photo-EOCAS (Electrophile-Olefin Combination Aromatic Substitution) mechanism [32], and is initiated by a PET reaction between an electron-rich aromatic and an electron-poor olefin, as illustrated in Scheme 3.14.
