Copper‐Catalyzed Ring‐Opening Hydrosilylation and Hydroboration of Arylidenecyclopropanes

Comprehensive Summary Arylidenecyclopropanes (ACPs) are highly strained substrates that can be readily utilized for diverse transformations. This study showcases the outcomes of copper‐catalyzed ring‐opening hydrosilylation and hydroboration reactions of ACPs, showcasing precise cleavage of C—C bonds. The reaction presents an effective and convenient method for producing homoallylic silanes and boronates.
