Web11 nov. 2024 · Lithium tri-tert-butoxyaluminum hydride is a white powder with a melting point of 319°C, which is sublimated under vacuum at 280°C. It is soluble in ethylene glycol dimethyl ether, diglyme and tetrahydrofuran, and slightly soluble in ether. Stable in dry air, hydrolyzed slowly in moist air. WebFor instance, lithium tri- tert -butoxy)aluminium hydride (LTBA) reduces aldehydes and ketones selectively in the presence of esters, with which it reacts extremely slowly. [20] (8) α,β-Unsaturated ketones may be reduced selectively in a 1,2 or 1,4 sense by a judicious choice of reducing agent. WebUpon completion of the reaction, she evaporates the thionyl chloride to isolate compound A. She treats compound A with a stoichiometric amount of lithium tri-tert-butoxyaluminum hydride at –78 °C in diethyl ether, producing compound B. Adding water, she isolates her product, compound C.
