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
dichloromethane;
the acid is added to a stirred soln. of the bismuth acetate in CH2Cl2 at room temp., reaction time 30 min; filtd., the solvent is distd., the residue is recrystd. (CH2Cl2/petroleum ether);
DOI:10.1080/00397919408020774
- Guidance literature:
-
With
tert.-butylhydroperoxide;
In
diethyl ether;
byproducts: t-BuOH, H2O; t-BuOOH (5 mmol) was added dropwise to a stirred cold (5-10°C) soln. of Ph3Bi (5 mmol) and carboxylic acid (10 mmol) in Et2O; the mixt. was kept in the dark for 24 h at room temp.; the solvent was distd. off under reduced pressure; purifn. by recrystn. (CHCl3/hexane);

- Guidance literature:
-
With
ozone;
In
further solvent(s);
ozonized oxygen passed into soln. of Ph3Bi in ethyl trifluoroacetate for 6 min at -78°C to give a suspn.; filtration through Celite; evapn. left pure Ph3Bi(OCOCF3)2 as confirmed 1H NMR spect.; elem. anal.;
