Technology Process of Methylidynetris(trimethylstannane)

There total 4 articles about Methylidynetris(trimethylstannane) 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: 0.5%

3,exo-4-dibromobicyclo{3.2.1}octa-2,6-diene + trimethyltin(IV)chloride (1066-45-1) → Tris-(trimethylstannyl)-methan (56177-42-5)

Guidance literature:

With lithium; In tetrahydrofuran; water; O2-free atmosphere; Li (cuttings) and Me3SnCl in THF (25°C, 15 h), filtrate added to dibromobicyclooctadiene (THF, -78°C)(molar ratio 1.54), stirring (room temp.), poured into water, extn. (pentane), drying (Na2SO4);other products; monitored by (1)H-NMR;

Reference yield:

(trimethylstannyl)lithium (17946-71-3) → Tris-(trimethylstannyl)-methan (56177-42-5)

Guidance literature:

With chloroform; In tetrahydrofuran; prepd. by react. of CHCl3 with Me3SnLi in dry THF as in D.R. Dimmel, C.A. Wilkie and P.J. Lamothe, Org. Mass. Spect., 10 (1975) 18; distd. at <0.8 mmHg, purified by crystn. from ethanol;

DOI:10.1016/0022-328X(84)80108-4

Reference yield:

Bromoform (75-25-2) + trimethyltin(IV)chloride (1066-45-1) → bis(trimethylstannyl)methane (16812-43-4) + Tris-(trimethylstannyl)-methan (56177-42-5)

Guidance literature:

With magnesium; In tetrahydrofuran; careful addn. of CHBr3 in dry THF to the Grignard reagent from Me3SnCl and Mg turnings; distd. at <0.8 mmHg, purified by crystn. from ethanol;

DOI:10.1016/0022-328X(84)80108-4
