Three‐component reactions can directly convert three reactants into the desired products in one pot and thus greatly shorten the synthetic path. Recently, transition‐metal catalysis has been applied in the difunctionalization of alkenes and remarkable progress has been achieved to facilitate the construction of a wide range of functional molecules with high atom‐ and step‐economic efficiency. This Focus Review highlights recent advances in this field.
