Title: Aluminum Hydride
CAS Registry Number: 7784-21-6
Molecular Formula: AlH3
Molecular Weight: 30.01
Percent Composition: Al 89.91%, H 10.08%
Literature References: Mild, selective reducing agent. Prepd by treating lithium hydride with an ether solution of aluminum chloride: A. E. Finholt et al., J. Am. Chem. Soc. 69, 1199 (1947). Brief review: K. Lopinti, Synlett 2005, 2265-2266.
Properties: Colorless solid, nonvolatile, probably highly polymerized and containing residual ether which cannot be completely removed.
Use: As catalyst for polymerizations; reducing agent. Lithium aluminum hydride, q.v. is a more powerful reagent because of its greater soly.
