Description and Uses

Lithium tri-tert-butoxyaluminum hydride is less reactive than lithium aluminum hydride (LAH) and is very useful in selective reductions of acyl halides, aldehydes, ketones, and esters. It is an important raw material and intermediate used in organic synthesis, pharmaceuticals, agrochemicals and dye stuff. LAH, is a reducing agent commonly employed in modern organic synthesis.
