Ruthenium-Catalyzed ortho-Alkenylation of Aroylgermanes

In this communication, a ruthenium-catalyzed ortho-alkenylation of acylgermanes with electron-deficient alkenes through direct C-H bond activation has been developed. With acylgermane as the directing group, this method provides a straightforward access to diverse acylgermanes derivatives with good functional group tolerance and site-selectivity under mild reaction conditions.
