Technology Process of (SR,RS),(SS,RR)-[Re(η(5)-C5H5)(NO)(PPh3)(CH2CH(OMe)Me)]

There total 1 articles about (SR,RS),(SS,RR)-[Re(η(5)-C5H5)(NO)(PPh3)(CH2CH(OMe)Me)] 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:

[(η(5)-C5H5)Re(NO)(PPh3)(H2C=CHCH3)]BF4 + sodium methylate (124-41-4) → (E)-(η(5)-C5H5)Re(NO)(PPh3)(CH=CHCH3) + (SR,RS),(SS,RR)-[Re(η(5)-C5H5)(NO)(PPh3)(CH2CH(OMe)Me)] (167864-28-0,167938-45-6)

Guidance literature:

With methanol; In tetrahydrofuran; methanol; addn. of excess NaOMe (in MeOH) to Re-complex (in THF; RS,SR/RR,SS=70:30) with shaking, then 10 min (NMR monitoring); solvent removal (oil pump), extn. into Et2O, solvent removal (oil pump), re-pptn. from CH2Cl2/hexane; diastereomer mixt. (SR,RS/SS,RR=77:23) not sepd., detd. by (1)H-, (13)C- and (31)P-NMR spectroscopy; elem. anal.;
