Your CHOice! An efficient RhIII-catalyzed dehydrogenative Heck reaction (DHR) of salicylaldehydes with different classes of olefins extends the oxidative Heck reaction to aldehyde CH bonds. Several structural motifs similar to natural products and bioactive molecules such as aurones, flavones, 2′-hydroxychalcones, and flavanones could be efficiently produced. Initial mechanistic studies give insight into the reaction mechanism.
