Technology Process of Cp(CO)2Re=C(Tol)CCCH₂CH₂CH₂CCH

There total 2 articles about Cp(CO)2Re=C(Tol)CCCH₂CH₂CH₂CCH which guide to synthetic route it. 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:

Reference yield: 35.0%

{Cp(carbonyl)2rhenium(CTol)}{BCl4} (106865-70-7) + LiCCCH2CH2CH2CCLi → Cp(CO)2Re=C(Tol)CCCH2CH2CH2CCH (416872-63-4) + [Cp(CO)2Re]2[η2,η2-TolCCC(CH2CH2CH2)=CCCTol] (416872-65-6)

Guidance literature:

With zinc dibromide; In tetrahydrofuran; BrZnCCCH2CH2CH2CCZnBr from LiCCCH2CH2CH2CCLi and ZnBr2 in THF was added to (Cp(CO)2ReCTol)BCl4 in THF at -35°C; silica gel column (hexane:Et2O 4:1), evapn., dissoln. in CH2Cl2 andstirring for 2 h, tlc (silica, hexane:Et2O 4:1);
