What is Lithium tri-Tert-butoxyaluminum Hydride?

Lithium tris(tert-butoxy)aluminum hydride (LTBA) is one of the reducing agents commonly used in laboratories. This reagent can provide one equivalent of hydride ions in the reaction, so it needs to be added in an equivalent amount according to the theoretical amount of hydrogen atoms required for the reduction of the substrate.

Lithium tri-Tert-butoxyaluminum Hydride Uses

Lithium 3-tert-butyl hydride solution as a nucleoside prodrug for selective synthesis of steroids for the treatment of hepatitis C virus (HCV)-hydroxy-d-2′-deoxy-2′-sulfo-fluoro-2′-chloro- C-methyl-3′, 5′-cyclophosphate
Lithium tert-butoxyaluminum hydride is a mild and also very discerning lowering agent that decreases ketones, aldehydes and also acid chlorides in diethyl ether or diglyme at 0 ° C, does not decrease fat esters as well as nitriles, however can reduce Phenyl esters of fats and alicyclic acids, lowered tetrahydrofuran (ring opening). It is used as a decreasing representative in medicine, flavors, pesticides, dyes and various other great natural synthesis.

Lithium tri-tert-butoxyaluminum hydride Properties

Lithium tri-tert-butoxyaluminum hydride is a white powder with a melting point of 319°C, which is sublimated under vacuum at 280°C. This product is soluble in ethylene glycol dimethyl ether, diglyme and tetrahydrofuran, and slightly soluble in ether. Stable in dry air, hydrolyzed slowly in moist air. It is a mild and highly selective reducing agent. Ketones, aldehydes and acid chlorides can be reduced in diethyl ether or diglyme at 0°C, fatty acid esters and nitriles are not reduced, but phenyl esters of fatty acids and alicyclic acids can be reduced.

Preparation of Lithium Tri-tert-butoxy Aluminum Hydride

Lithium tri-tert-butoxyaluminum hydride has attracted extensive interest from scientists and technicians all over the world due to its wide use. Research on the improvement of the synthesis method of lithium tri-tert-butoxyaluminum hydride is in the ascendant. In the prior art, lithium hydride is prepared by using metal lithium as a raw material, and lithium hydride is reacted with aluminum trichloride to prepare lithium aluminum hydride. Lithium aluminum hydride reacts with tert-butanol in ether to prepare tri-tert-butoxy lithium aluminum hydride. Method 1. Bake a 2-liter three-necked flask equipped with a stirrer, a constant pressure dropping funnel and a condenser containing dry ice and blow it with dry nitrogen; A solution of 600 ml of aluminum hydride (0.32 mol) in ether was placed, and 74 g (1.00 mol) of tert-butanol was added dropwise with stirring. Most of the ether was decanted and the remainder and excess t-butanol were removed under reduced pressure. The product was 81.0 g, essentially quantitative yield. Method 2. We have carried out a lot of synthesis research. The main improvement points are: replacing the expensive metal lithium with cheap metal sodium and lithium chloride, reducing the reaction temperature by nearly 200 °C, at the same time, using cheap and relatively safe methyl tertiary Butyl ether is used as the reaction medium instead of high-priced and flammable ether, which not only reduces the production cost, but also improves the safety of the technological process.
