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
trifluoroacetic acid;
diazonium salt in trifluoroacetic acid was added dropwise to a boiling mixture of carborane, hexafluorobenzene and trifluoracetic acid, refluxed for 30 min; evaporated to dryness, solid dissolved in acetone, soln. treated with ether, filtered, recrystallized (acetone-ether);
- Guidance literature:
-
With
aniline; sodium nitrite;
In
trifluoroacetic acid;
aniline in trifluoroacetic acid was diazotized with NaNO2, solution was mixed with carborane in hexafluorobenzene, dropwise addn. of trifluoroacetic anhydride, refluxed for 30 min; solvent removed under vacuum, treated with pentane-ether, extracted with water, treated with HBF4, extracted with nitromethane-chloroform, evaporated, treated with ether, filtered, recrystallized (acetone-ether), elem. anal.;
- Guidance literature:
-
With
(CF3COO)2O;
In
water; trifluoroacetic acid;
addn. of carborane, C6F6 to diazonium-compd. (prepd. from aniline in CF3COOH at 0°C by addn. of NaNO2) with stirring, addn. of (CF3COO)2O, heating at reflux, evapn., addn. of pentane-ether (2:3), extn. of org. layer with H2O, addn. of 40% HBF4; extn. with 3:1 MeNO2-CHCl3, evapn. (vac.), pptn. by addn. of ether to the residue, purifn. by passage through alumina in CH2Cl2, repptn. from acetone by addn. of ether; elem. anal.;
