Technology Process of Selenium dicyanide

There total 3 articles about Selenium dicyanide 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:

trimethylsilyl cyanide (7677-24-9) + selenium(IV) fluoride (13465-66-2,271781-78-3) → ethanedinitrile (460-19-5,25215-76-3) + selenium(II) dicyanide (2180-01-0) + selenium(IV) tetracyanide (1043566-23-9)

Guidance literature:

In dichloromethane; byproducts: (CH3)3SiF; (Ar, Schlenk) a soln. of SeF4 in CH2Cl2 was treated with (CH3)3SiCN at -50°C dropwise, stired for 15 min; not sepd., detected by spectra;

DOI:10.1021/ic801011g

Reference yield:

dicyanodiselenide (27151-67-3) → selenium (7782-49-2) + selenium(II) dicyanide (2180-01-0)

Guidance literature:

In decalin; byproducts: paraselenocyanogen; heating for 2 h at 210 °C and 1 h at 180 °C; Se(CN)2 sublimate was deposited in refrigerator, paraselenocyanogen ppt. was settled and decanted, washed several times with CH2Cl2, dried in air;

DOI:10.1016/S0277-5387(00)00304-1

Reference yield:

diethyl ether (60-29-7,927820-24-4) + triselenium dicyanide (2179-96-6) → hydrogen cyanide (74-90-8) + selenium(II) dicyanide (2180-01-0)
