Metal Nanoclusters as Catalysts for Organoborane Synthesis: Recent Advances and Mechanistic Insights

The development of metal nanoclusters (NCs) has attracted significant interest due to their applications in photonics, biology, electronics, and catalysis. Their ultrasmall size, tunable structures, and well‐defined structure–property correlation make them attractive tool in the field of catalysis. This review article provides a comprehensive overview of the synthesis and characterization of metal NCs, with particular emphasis on their applications in catalytic CB bond‐forming reactions, especially the hydroboration, dihydroboration, and carboboration of alkynes. Furthermore, mechanistic studies are emphasized to elucidate the reaction pathways underlying these transformations. Considering the growing advancements in this field, the insights presented in this review are expected to inspire future developments in the design of novel metal NCs for diverse organic transformations.
