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 is also more thermally stable and not pyrophoric.

As shown in the scheme above, it can be used to reduce propargyl alcohols to allyl alcohols via hydrometallation. The alkenylaluminum intermediate is reactive towards various electrophiles, thus can be functionalized further. Unlike DIBAL, Red-Al gives trans-substituted products.
