Dichlorobis(1,4-diazabicyclo[2.2.2]octane)(tetrahydroborato)zirconium(IV), [Zr(BH_4)_2Cl_2(dabco)_2](ZrBDC), as a new, stable, and versatile bench top reducing agent: reduction of imines and enamines, reductive amination of aldehydes and ketones and

摘要

The reducing agent is easily prepared in an almost quantitative yield from commercially available starting materials. This compound is stable under mild aqueous conditions (pH 4-6) and survives in H_2O for several days without losing its reducing abilities. ZrBDC has been successfully used for the reduction of imines and enamines, reductive amination of aldehydes and ketones, and reductive methylation of amines.
