Abstract
The present invention provides compositions comprising a metal amidoborane and an amine, and processes for preparing the metal amidoborane compositions. In particular, the process comprises contacting ammonia borane with a metal amide in the presence of an amine solvent to form the metal amidoborane composition. The invention also provides methods for generating hydrogen, wherein the method comprises heating the metal amidoborane composition such that hydrogen is released.
Claims8
A process for preparing a compound comprising Formula (III), the process comprising contacting a compound comprising Formula (I) with a compound comprising Formula (II) in the presence of an amine solvent comprising NR1R2R3 to form the compound comprising Formula (III) according to the following reaction scheme:
- wherein:
- M is a metal selected from the group consisting of an alkali metal, an alkaline earth metal, and a transition metal;
- R1, R2, R3, R4, and R5 are independently selected from the group consisting of hydrogen, hydrocarbyl, substituted hydrocarbyl, and silyl, provided any two of R1, R2, and R3 together may form a ring or a ring system selected from the group consisting of carbocyclic, heterocyclic, aryl, and heteroaryl, and R4 and R5 together may form a ring or a ring system selected from the group consisting of carbocyclic, heterocyclic, aryl, and heteroaryl;
- and
- x is an integer equal to the valence of M.
