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
methanol; isopropyl alcohol;
under exclusion of air and moisture, in purified Ar; the P-compd. is dissolved in i-propanol and heated to boiling, a filtered soln. of the Co-compd. in a i-propanol/methanol mixt. (2:1) is added dropwise within 30 min, refluxing for 4 h; pptn. after cooling to room temp., washing with cold i-propanol for two times and drying in vac., elem. anal.;
- Guidance literature:
-
In
tetrahydrofuran;
byproducts: KI; under exclusion of air and moisture, in purified Ar; the Co-compd. is dissolved in THF and a soln. of the B-compd. in THF is added at -30°C, the solvent is evapd. at -30°C to the half of the initial volume; cooling down to -60°C, pptd. KI is filtered off, solvent is removed from soln. (-30°C, vac.), addn. of cold Et2O, the ppt. is filtered off, washed with cold n-hexane (three times), dried in vac. at -30°C (several days), elem. anal.;
