The eco-friendly and highly efficient catalytic hydroboration of nitriles has been elucidated by using organic aluminum hydrides.

Herein, Al-catalyzed hydroboration of carbonates, esters, carboxylic acids, and CO2, with HBpin, is described, which provides a new route for the reduction of CO group compounds. We also conducted an in-depth study of the reduction mechanism of carbonate.

Highly efficient and selective hydroboration of nitriles and carbodiimides with pinacolborane (HBpin) is achieved by using the simple and convenient n‐BuLi as a catalyst. Solvent‐free and good functional group tolerance under mild conditions have been achieved. A possible mechanistic pathway of the n‐BuLi catalyzed hydroboration of nitriles with HBpin is proposed.

Commercially available compound ZnEt2 acts as an efficient precatalyst for the solvent-free hydrophosphinations of heterocumulenes using Ph2PH as reagent. As far as we knew, this has been not reported in...

The catalysts used to catalyze the hydroboration of nitriles or carbodiimides usually have some disadvantages such as complex structure, high cost, large pollution of environment and so on. It is an important development direction to use the main group metals instead of the transition metals to reduce the costs and realize green catalysis. In this paper, using NaH or NaOH as a catalyst, an efficient reaction of nitrile or carbodiimide with pinacol borane (HBPin) has been achieved. It was found that 3.5 mol% of NaH participated in the hydroboration reaction in a simple and effective method under slight solvent-free circumstances. In addition, intermolecular chemoselectivity hydroboration of nitrile and substrates with different functional groups was also investigated by employing three different catalysts. This reaction uses the inorganic alkali with simple structure, commercially available and low cost to synthesize organoborane compounds, which provides ideas for industrial development.
