Beschreibung

Allgemeine Beschreibung

Lithium dimethylaminoborohydride is a reagent exhibiting dual properties like a metal hydride and nitrogen nucleophile. It is generally considered as an alternative to lithium aluminum hydride (LAH) for the reduction of carbonyl compounds, amides, and lactams.

Anwendung

Lithium Aminoborohydride (LAB) Reagents

Reactant for:

• B-H oxidative addition reactions
• Reduction and amination reactions
• Reduction of N-alkyl lactams
• Synthesis of tertiary amine-boranes

Capable of reducing a variety of fuctional groups.

LABs can transfer the amine moiety, as in the case of the reaction with halopyridines and primary alkyl methanesulfonates.
