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: 87.0%

Ir4(CO)10(μ-bis(diphenylphosphano)methane) + water (7732-18-5) + bis(triphenylphosphine)iminium chloride (21050-13-5) → bis(triphenylphosphoranylidene)ammonium tetrahedro-nonacarbonyl(hydrido)(μ3-bis(diphenylphosphino)methane)tetrairidate (286385-08-8)

Guidance literature:

With 1,8-diazabicyclo[5.4.0]undec-7-ene; In dichloromethane; byproducts: (DBUH)Cl, CO2; soln. of (Ir4(CO)10(μ-dppm)) and PPNCl in CH2Cl2 under CO was cooledto -10°C and DBU was added, soln. was stirred for 2 h; cold isopropanol was added and volume of soln. was reduced, ppt. was recrystd. at -30°C from CH2Cl2/isopropanol, crystals were washed with cold isopropanol and pentane; elem. anal.;
