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.

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] is a very good reducing agent and a good substitute for lithium aluminum hydride (LAH). Compared to LAH, red-al is not sensitive to oxygen (but to moisture) and is very soluble in ether, THF, 1,4-dioxane, toluene and benzene.

Red-Al is an efficient chelation-controlled reducing reagent for acyclic acetal-protected R-hydroxy ketones. Typically, high diastereomeric ratios and yields can be achieved for the synthesis of 1,2-anti-diols.

The three most common Al hydride employed for amide reduction are lithium aluminium hydride (LAH), Sodium bis(2-methoxyethoxy) aluminum hydride (Vitride, Red –Al) and diisobutyl aluminium hydride (DIBAL). Reactivity is LAH > Red –Al > DIBAL.

Sodium bis (2-methoxyethoxy)aluminium hydride (SMEAH; trade names Red-Al, Synhydrid, Vitride) is a hydride reductant with the formula NaAlH 2 (OCH 2 CH 2 OCH 3) 2. The trade name Red-Al refers to its being a red ucing al uminium compound. It is used predominantly as a reducing agent in organic synthesis.

红铝是一种强力的氢化物还原剂，可以将羧酸酸酐及内酯还原成二元醇，也可将酰胺、腈或是亚胺及大部分含氮的有机化合物还原成对应的胺。Red-Al是英文 Reducing AluminiumCompound的缩写，中文意思为“还原性铝化合物”。

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 …
