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
diethyl ether; pentane;
byproducts: LiCl, C6H5Bi(CH2CH3)2; react. under N2 in dry, N2-satd. solvents; dropwise addn. of Li-compd. in pentane to a stirred suspn. of Bi-compd. in ether (-70 to -65°C, 1 h), stirring for 0.5 h at -70°C, warming to room temp.; evapn. (vac.), reslurring of residue with benzine and decantation (3 times), evapn. of combined solns. (room temp., vac.), distn. of oily bismutane at 1E-1 to 1E-2 Torr; elem. anal.;

With
potassium;
In
tetrahydrofuran;
byproducts: ethylbenzene; a THF soln. of Ph3Bi was treated with K under Ar, mixt. was stirred forseveral hours at 25°C, at -40°C EtBr was added slowly; PhEt and THF were removed in vacuo, residue extd. with n-pentane-toluene, ext. evapd., residue was purified by Kugelrohr distn. at 130°C; elem. anal. for Ph2BiEt, it was contaminated with a small amt. of PhBiEt2 according to mass spectral data;
