There total 4 articles about 3,5-Heptanedione, 2,2,6,6-tetramethyl-, ion(1-), bismuth(3+) 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:
- Guidance literature:
-
In
toluene;
byproducts: HN(Si(CH3)3)2; diketone was added to soln. of bismith comples in THF, stirred for 30 min; evapd., dried in vac. at 60°C for 2 h, elem. anal.;
DOI:10.1039/b918175j
- Guidance literature:
-
With
sodium isocyanate;
In
tetrahydrofuran;
byproducts: NaCl, methyl carbamate; with light exclusion, THF soln. BiCl3 was added to THF suspn. of NaOCN, THF soln. of 3 equiv. of oxo-compd. was dropped, 80 °C for 6 h; Na-salts were filtered off, solvents were removed, methyl carbamate was sublimed in vac. at 60 °C, recrystn. from THF, elem. anal.;
- Guidance literature:
-
In
tetrahydrofuran;
BiCl3 in THF was added to Nadpm in THF, under argon, after 2 h evaporated to dryness; extracted by hexane or CH2Cl2, sublimation, elem. anal.;
DOI:10.1016/S0277-5387(00)80209-0
