Recent Advances in the Chemistry of Lithium Aminoborohydrides

摘要

Lithium aminoborohydrides (LABs) are a new class of powerful,selective,and air-stable reducing agents.LABs can be prepared as solids or 1-2 M THF solutions,or can be generated in situ for immediate use.Since LABs can be synthesized from any primary or secondary amine,the steric and electronic environments of these reagents can be easily controlled.Solid LAB reagents can be used in dry air as easily as sodium borohydride,and they maintain their chemical reactivity for at least 6 months when stored at 25 deg C under nitrogen or dry air.
