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;
stirring a soln. of Cr-complex in toluene at room temp. (under N2 or in vacuo), monitoring by IR; filtn., removal of solvent in vacuo, dissolution of residue in a minimum amount of CH2Cl2, addn. of hexane until soln. turned cloudy, cooling to -20°C, filtn., drying in vacuo, elem. anal.;

- Guidance literature:
-
In
toluene;
dropwise addn. of a soln. of Cr-complex to a suspn. of (C5H5)Tl in toluene, refluxing for 16 h (under N2 or in vacuo); filtn., evapn. to dryness in vacuo, redissolution of residue in a minimum amount of CH2Cl2, chromy. on silica gel, elution with CH2Cl2, concn., addn. of hexane until the soln. turned cloudy, cooling to -20°C give crystals;
