Technology Process of HIr(PPh₃)2(CO)2

There total 11 articles about HIr(PPh₃)2(CO)2 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: 90.0%

trans-MeOIr(CO)(PPh3)2 (94070-38-9) → HIr(PPh3)2(CO)2 (17250-59-8) + Methyl formate (107-31-3)

Guidance literature:

With formaldehyd; In tetrahydrofuran; Trans-MeOIr(CO)(PPh3)2 and paraformaldehyde are dissolved in THF and stirred ( 2 days, room temp.).; React. is monitored by IR. Removing of solvent yields yellow solid, chromy. on Florisil (eluant: THF/cyclohexane).;

Reference yield: 75.0%

trans-MeOIr(CO)(PPh3)2 (94070-38-9) + acetaldehyde (75-07-0,9002-91-9) → HIr(PPh3)2(CO)2 (17250-59-8) + acetic acid methyl ester (79-20-9) + propanoic acid methyl ester (554-12-1)

Guidance literature:

In cyclohexane; in dry box onto the degassed (vac.) soln. of complex (in a pressure tube fitted with a Teflon stopcock) CH3CHO distilled, 5 d reacted at room temp.; not isolated, spect. detection by IR and NMR in the soln.;

DOI:10.1021/om00105a034

Reference yield:

trans-MeOIr(CO)(PPh3)2 (94070-38-9) + acetaldehyde (75-07-0,9002-91-9) → HIr(PPh3)2(CO)2 (17250-59-8) + acetic acid methyl ester (79-20-9) + ethyl acetate (141-78-6)

Guidance literature:

In benzene-d6; byproducts: CH3OH, CH4; Distn. of degassed benzene-d6 into complex, room temp.; Monitored by NMR, GC.;
