556-91-2 Usage
Description
Aluminum tert-butoxide, also known as aluminum tert-butylate, is an organoaluminum compound with the chemical formula (t-BuO)3Al. It is a colorless, crystalline solid that is soluble in organic solvents and is commonly used as a reagent in various organic synthesis reactions.
Used in Chemical Synthesis:
Aluminum tert-butoxide is used as a reagent in the Oppenauer oxidation of alcohols to ketones. It is also used in the Meerwein-Ponndorf-Verley reduction of ketones. Additionally, it is involved in the preparation of 1,1,2-triethoxyethene by reacting with 1,1,2,2-tetraethoxyethane followed by the elimination of alcohol.
Used in Dealcoholation of Orthoesters:
Aluminum tert-butoxide is utilized in the dealcoholation of orthoesters, a process that involves the removal of an alcohol molecule from the orthoester to form a more stable compound.
Purification Methods
Crystallise it from *C6H6 and it sublimes it at 180o. [McElvain & Davie J Am Chem Soc 73 1400 1951, Beilstein 1 IV 1612.]
Check Digit Verification of cas no
The CAS Registry Mumber 556-91-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,5 and 6 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 556-91:
(5*5)+(4*5)+(3*6)+(2*9)+(1*1)=82
82 % 10 = 2
So 556-91-2 is a valid CAS Registry Number.

Oxidation of organic sulfides and disulfides with a tert-butyl hydroperoxide-aluminum tri-tert-butoxide system
Zaburdaeva,Dodonov
, p. 185 - 187 (2011/09/12)
Methyl phenylethynyl and phenyl phenylethynyl sulfides are selectively converted into methyl phenylethynyl and phenyl phenylethynyl sulfones, respectively, under the action of system tert-butyl hydroperoxide-aluminum tri-tert-butoxide in benzene at 20 °C. The analogous oxidation of diphenyl disulfide results in S-phenyl benzenethiosulfonate.
Reaction of organoelement hydrides R3EH (E = Si, Ge) with metal tert-butylate (M = Al, Ti)-tert-butyl hydroperoxide oxidative systems

Trialkyl(aryl)silanes and -germanes effectively react with metal (Al, Ti) tert-butylate-tert-butyl-hydroperoxide under mild conditions (room temperature, benzene or tetrachloromethane) mainly by the element-hydrogen bond. The character of the products depends on the nature of the element, the structure of the radical bound to it, and the solvent. The process is radical in nature. It includes the stages of formation of element-centered radicals and their reaction with the oxygen generated by the system. The intermediate organometallic peroxides can also acts as oxidants for the element (Si, Ge)-hydrogen bonds. 2005 Pleiades Publishing, Inc.
