Abstract:Hydroboration is one of the main ways to synthesize organoboron compounds, which has received much attention because of its mild conditions, simple operation and high atomic utilization. Materials containing noble metals such as Rh, Ir, and Pb have been the primary choice catalysts for hydroboration in the past decades, but their high cost and toxicity have limited their widespread application. In the last decade, alkaline earth metals and cheap transition metals such as Fe, Co and Ni have flourished in the field of catalytic hydroboration because of their abundant reserve, low price and high catalytic performance, thus exhibiting have a broad application potential. This paper focuses on the research progress of transition metal and alkaline earth metal-based materials catalyzing hydroboration of unsaturated hydrocarbons in recent years.
