Technology Process of Dichlorobis(tetrahydrofuran)zinc

There total 1 articles about Dichlorobis(tetrahydrofuran)zinc 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: 82.3%

zinc(II) chloride (7646-85-7,24359-56-6) → zinc chloride *2 tetrahydrofuran (24640-76-4)

Guidance literature:

In tetrahydrofuran; inert atm.; stirring (1 h, room temp.); layering (n-pentane); elem. anal.;

Reference yield: 73.0%

zinc chloride *2 tetrahydrofuran (24640-76-4) + dimesitylmagnesium (99107-86-5) → bis(2,4,6-trimethylphenyl)-zinc (73681-65-9)

Guidance literature:

In tetrahydrofuran; 1,4-dioxane; under Ar ZnCl2(thf)2/THF stirred at room temp. for 2 h, at 50°C for 1 h, MgMes2/dioxane/THF added, stirred; solvent removed, Et2O added, filtered, residue washed (heated ether), elem. anal.;

Reference yield: 62.0%

1,2-bis(dimesitylphosphanylamino)benzene (869117-55-5) + zinc chloride *2 tetrahydrofuran (24640-76-4) → [ZnCl2(1,2-(N(PH(2,4,6-Me3C6H2)2))2C6H4-κ2N,N')]*0.5THF

Guidance literature:

In dichloromethane; under N2 atm. ligand in CH2Cl2 was added dropwise to soln. (ZnCl2(THF)2)in CH2Cl2 and stirred for 1 h; react. mixt. was concd. in vacuo and layered with petroleum ether, room temp.;
