Technology Process of fac-{manganese(Cl)(carbonyl)3(dppm)}

There total 3 articles about fac-{manganese(Cl)(carbonyl)3(dppm)} 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: 71.0%

pentacarbonylchloromanganese(I) (14100-30-2) + bis-diphenylphosphinomethane (2071-20-7) → fac-{manganese(Cl)(carbonyl)3(dppm)} (60305-98-8)

Guidance literature:

In chloroform; (N2); stirring (exclusion from light, gentle reflux, ca. 5 h); redn. of volume, addn. to stirred ice cold hexane, filtration, washing (hexane), drying (vac.); elem. anal.;

Reference yield: 25.0%

bis(benzonitrile)palladium(II) dichloride (15617-18-2,39958-10-6,14220-64-5) + sodium pentacarbonyl manganate (13859-41-1) + bis-diphenylphosphinomethane (2071-20-7) → dimanganese decacarbonyl (10170-69-1) + μ-bis(diphenylphosphino)methane-P:P'-octacarbonyldimanganese(Mn-Mn) (37523-60-7) + fac-{manganese(Cl)(carbonyl)3(dppm)} (60305-98-8) + PdCl((C6H5)2PCH2P(C6H5)2)2Mn(CO)3

Guidance literature:

In tetrahydrofuran; byproducts: NaCl, PhCN; (N2), soln. of the Mn-complex added to a cooled (-78°C) and stirred soln. of the Pd-complex, dppm added after 0.25 h, temp. raised to ambient, further stirred for 6 h, filtered, impregnated on silica gel, evapd. to dryness; chromd. on silica gel, Mn2(CO)10, PhCN eluted (pentane), Mn2(CO)8(dppm) eluted (pentane/toluene (2:1)), MnCl(CO)3(dppm) and PdMn-complex eluted toluene/THF (95:5)), recrystd. from THF/n-hexane and CH2Cl2/n-hexane, MnCl(CO)3(dppm) further eluted with THF;

Reference yield:

{(palladium)2(manganese)2(carbonyl)8(μ3-carbonyl)(μ-dppm)2} (86028-11-7) + tetraethylammonium chloride (56-34-8) → fac-{manganese(Cl)(carbonyl)3(dppm)} (60305-98-8) + {(palladium)2manganese(Cl)(carbonyl)3(μ3-carbonyl)(μ-dppm)2} (111026-27-8)

Guidance literature:

In tetrahydrofuran; Under N2, addn. of (NEt4)Cl to suspn. of freshly prepd. Pd2-Mn2-complex, stirring (1,5 h), mixt. turns brown-green.; Evapn. in vac., filtn., washing of residue (H2O), drying, partly sol. in THF as brown-green soln., addn. of n-hexane gives mixt. of Pd2-Mn-complex and unidentified substance (IR), mother liquor gives fac-Mn-complex (IR, (1)H-NMR).;
