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:
-
With
triethylamine;
In
methanol;
byproducts: NHEt3Cl; stirring of a soln. of Sb-compd. in anhyd. methanol and isatin-compd. in methanol in presence of triethylamine at room temp. (30°C) for 4 h under an anhyd. and O2 free N2 atmosphere; filtn. under N2, removal of NEt3HCl, concn. of filtrate in vacuo, recrystn. from petroleum ether, elem. anal.;
- Guidance literature:
-
With
carbon disulfide;
In
carbon disulfide;
refluxing Sb-compd. with an excess of CS2 for 8 h under N2 atmosphere; removal of volatiles in vacuo, monitoring by IR;
- Guidance literature:
-
With
bromine;
In
tetrachloromethane;
slow addn. of bromine in CCl4 to a soln. of Sb-compd. in CCl4 at -5°C over 30 min in a N2 atmosphere, colour of bromine disappears readily after each addn., but at the end a light brown colour persists; warming to room temp., removal of volatiles in vacuo, monitoring residue by IR;
