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:
- Guidance literature:
-
In
tetrahydrofuran;
byproducts: LiBr; Ar atmosphere, addn. Sn-compd. to soln. of dibromoalkane (temp. < -70°C); addn. water (room temp.), recrystn. (n-hexane); elem. anal.;
- Guidance literature:
-
In
neat (no solvent);
byproducts: Me3SnBr; Ar atmosphere, 2 equiv Me2SnCl2 heating (12 - 16 h, 90°C); removal Me3SnBr (40°C, 0.01 torr); elem. anal.;
- Guidance literature:
-
With
methyllithium;
In
tetrahydrofuran;
equimolar mixt. of distannylalkene and MeLi in THF was stirred at -78°C for 1-2 h under Ar, 1 equiv of Me3GeCl was added dropwise, stirred for 1 h, allowed to warm to room temp.; water was added, org. phase sepd., dried, solvent removed, residue was recrystd. from hexane;
