Technology Process of niobium(IV) iodide

There total 1 articles about niobium(IV) iodide 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:

niobium + iodine (7553-56-2,12190-71-5,8031-47-8) → niobium(V) iodide (13779-92-5) + niobium(IV) iodide (13870-21-8) + NbI3.2

Guidance literature:

In neat (no solvent); product ratio depends on temp.;

Reference yield: 85.0%

niobium(IV) iodide (13870-21-8) + 4,4-dimethyl-1-(1-methoxycyclohexyl)-1,3-pentanedione (170954-47-9) → tetrakis-(4,4-dimethyl-1-(1-methoxycyclohexyl)-1,3-pentanedionate)niobium(IV)

Guidance literature:

With diethylamine; In toluene; dry box, atmosphere of N2 saturated with amine at 40°C; mixture of NbI4 and ligand stirring (20 min), soln. of diethylamine addn., stirring (5 min), evapn.; residue treating with heptane, soln. filtration, filtrate cooling (-60°C), keeping several hours in N2 flow, ppt. filtration off, washing(heptane), drying; elem. anal.;

Reference yield: 80.0%
