2009年6月16日 · Sodium bis (2-methoxyethoxy)aluminumhydride, also called Red-Al, is an organoaluminium compound. It is used as a reagent in organic synthesis. Aluminum is the most abundant metal in the earth's crust and is always found combined with other elements such as oxygen, silicon, and fluorine. (L739, L740, L777)

Red-Al ®, or sodium bis(2-methoxyethoxy)aluminum dihydride (Vitride ®, SMEAH), is a versatile reducing agent and a good substitute for LiAlH 4 in many reactions. Red-Al ® is nonpyrophoric, although still moisture-sensitive, and is available in solution, allowing for easier handling compared to LiAlH 4 .

Red-Al ® sodium bis (2-methoxyethoxy)aluminum hydride [NaAlH 2 (OCH 2 CH 2 OCH 3) 2] is used as a versatile reducing agent in organic synthesis. It is used to reduce: Aldehydes, ketones, esters, and anhydrides to primary alcohols. Ketoximes and aldoximes to primary amines. Cyclic compounds such as lactones and epoxides to diols.

2017年5月23日 · Sodium bis(2-methoxyethoxy)aluminum hydride is a reducing agent sold with the common name Red-Al or Vitride. Red-Al can selectively reduce nitriles to aldehydes. It is more soluble in organic solvents (such as toluene) than LAH. It …

Sodium bis (2-methoxyethoxy)aluminium hydride (Red-Al) is comparable to LiAlH 4. The most important differences are found in the reduction of nitriles, which are selectively reduced to aldehydes, and in the reduction of aromatic aldehydes.
