Red-Al is a brand name of the Sigma-Aldrich company and the common trivial name for sodium bis (2-methoxyethoxy) aluminum hydride. It is an organoaluminum compound and is used as a good reducing agent in synthetic organic chemistry.
Reactions
Red-Al reduces lactones to diols and amides , nitriles , imines and most organic nitro compounds to the corresponding amines. Red-Al is usually used as a solution in toluene .
Comparison with lithium aluminum hydride
As an aluminum hydride, Red-Al is comparable to lithium aluminum hydride in terms of chemical reactivity . Red-Al, on the other hand, is easily soluble in aromatic solvents and so thermally stable that it remains reactive at temperatures above 200 ° C. It is also more stable to humidity and air. Applications have been described in which it was used for partial reductions.
