Technology Process of dicesium selenide

There total 6 articles about dicesium selenide 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: 98.0%

selenium (7782-49-2) + caesium (7440-46-2) → caesium selenide (31052-46-7)

Guidance literature:

In ammonia; NH3 (liquid); N2-atmosphere; addn. of 0.5 equiv. of Se to Cs soln. (-78°C), stirring for 1 h; slow warming to room temp., drying (vac., overnight), drying in flame;

Reference yield:

cerium (7440-45-1) + selenium (7782-49-2) → caesium selenide (31052-46-7)

Guidance literature:

In ammonia; NH3 (liquid); stoichiometric reaction of Cs with Se;

DOI:10.1021/ja034196p

Reference yield:

selenium (7782-49-2) + caesium (7440-46-2) → Cs2Se, I (31052-46-7) + Cs2Se, II, rhombic, FDD2 (31052-46-7)

Guidance literature:

With ammonia; In neat (no solvent); autoclave (100-300°C, 300-2000 bar, 3-12 d); product ratio of both modifications depending on reaction conditions;
