Technology Process of Lithium selenide

There total 9 articles about Lithium 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:

selenium (7782-49-2) + lithium triethylborohydride (22560-16-3) → lithium selenide (12136-60-6)

Guidance literature:

In tetrahydrofuran; (Ar); addn. of selenium to a soln. of boron compd. in THF with stirring;

DOI:10.1016/S0022-328X(01)00707-0

Reference yield:

selenium (7782-49-2) + lithium (7439-93-2) → lithium selenide (12136-60-6)

Guidance literature:

In ammonia; addn. of Se to a soln. of Li in liq. NH3 at -33°C, formation of Li2Se;;

DOI:10.1021/ja01412a021

Reference yield:

lithium selenate → lithium selenide (12136-60-6)

Guidance literature:
