a short chronological review on the syntheses of amine-boranes

since their discovery by burg and schlesinger in 1937, amine-boranes have enjoyed a rich preparative history and have experienced reinvigorated interest as valuable compounds. these borane complexes have been implemented in a variety of applications, spanning from reagents in organic syntheses to hydrogen storage materials. the importance of amine-boranes derives especially from their reductive abilities. given the utility of amine-boranes and their current resurgence, a mini review on their general properties and notable preparations is both timely and potentially of interest to organic and materials chemists alike.
