Technology Process of tris[(trimethylsilyl)methyl]aluminum

There total 5 articles about tris[(trimethylsilyl)methyl]aluminum which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

synthetic route:

Reference yield: 85.4%

aluminium bromide (7727-15-3) + trimethylsilylmethyllithium (1822-00-0) → tris[(trimethylsilyl)methyl]aluminum (41924-27-0)

Guidance literature:

In hexane; byproducts: LiBr; Li deriv. slowly adding with stirring to AlBr3 in hexane under Ar, LiBrpptg., refluxing for 12 h, solvent removing; isolated by vacuum distn., identified by NMR and IR spectra;

Reference yield: 17.0%

trimethylsilylmethyllithium (1822-00-0) + methylenebis (22949-82-2) → (C2H5O)2Li(CH2Si(CH3)3)2Al(CH2Si(CH3)3)2 (132911-56-9) + tris[(trimethylsilyl)methyl]aluminum (41924-27-0)

Guidance literature:

With diethyl ether; In pentane; byproducts: LiCl; under Ar, molar ratio Cl2AlCH2AlCl2:LiCH2SiMe3 1:4, reacted at -50°C, refluxed for 3 h; filtered, volume reduced in vacuo, in pentane insoluble reaction products treated with diethyl ether, filtered, solvent removed in vacuo, recrystallized from pentane;

Reference yield:

trimethylsilylmethyllithium (1822-00-0) → tris[(trimethylsilyl)methyl]aluminum (41924-27-0)

Guidance literature:

With aluminum (III) chloride; In 1,2-dichloro-ethane; pentane; at 20 ℃; for 0.5h;
