Technology Process of pentacarbonyl[1-methoxy-2-(methylthio)benzene-S]chromium⁽⁰⁾

There total 2 articles about pentacarbonyl[1-methoxy-2-(methylthio)benzene-S]chromium⁽⁰⁾ 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:

tricarbonyltrispyridinechromium(0) (27792-49-0,40250-96-2) + 1-methylsulfinyl-2-methoxybenzene (38452-13-0) → pentacarbonyl[1-methoxy-2-(methylthio)benzene-S]chromium(0) (156188-97-5) + (CO)5Cr(CH3OC6H4S(O)CH3) (156220-41-6)

Guidance literature:

With BF₃*OEt₂; In diethyl ether; byproducts: pentacarbonyl(pyridine)chromium(0), 1-methoxy-2-methylthiobenzene; under N2; BF3*OEt2 added to soln. of Cr compd. and org. ligand; mixt. stirred at room temp. for 1.75 h; N2-saturated H2O added to mixt.; extn. (Et2O); ext. dried (MgSO4) and concd. under reduced pressure to give a solid consisting of mixt. of starting org. ligand, the thiobenzene, SCr(CO)5 compd., and OSCr(CO)5 compd.(1H NMR spectrum (CDCl3));

Reference yield:

1-methylsulfinyl-2-methoxybenzene (38452-13-0) + chromium(0) hexacarbonyl (199620-14-9,13007-92-6) → Cr(CO)3(C6H4(SCH3)OCH3) (151042-13-6) + pentacarbonyl[1-methoxy-2-(methylthio)benzene-S]chromium(0) (156188-97-5)

Guidance literature:

In tetrahydrofuran; dibutyl ether; byproducts: 1-methoxy-2-methylthiobenzene; under N2; Cr compd. and org. ligand in Bu2O/THF (10/1) heated at 130 °C for 14.5 h; mixt. filtered; from filtrate, solvent removed to give an oil consisting of mixt. of org. compd., SCr(CO)3 compd., and SCr(CO)5 compd. (ratios 84/15/1, detected by 1H NMR spectrum (CDCl3));
