Technology Process of W₂(neopentyl)2(NMe₂)4

There total 1 articles about W₂(neopentyl)2(NMe₂)4 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:

1,2-W2Cl2(dimethylamido)4 (63301-81-5) + neopentyl lithium (7412-67-1) → W2(CH2C(CH3)3)2(N(CH3)2)4 (72286-69-2)

Guidance literature:

In toluene; under N2; to the dry components toluene was added at -78°C, stirred for 0.5 h, allowed to warm slowly to room temp., stirred further 3 h; toluene was stripped in vac., dried, hexane was added, filtrated, filtrate was collected, hexane was stripped, solid was sublimated at 85°C and 0.0001 torr; elem. anal.;

DOI:10.1021/ja00404a012

Reference yield: 70.0%

W2(neopentyl)2(NMe2)4 (72286-69-2) + p-Methoxybenzoic anhydride (794-94-5) → W2(neopentyl)2(O2CC6H4-p-OMe)4 (110142-83-1)
