this is a quote from rhodium:

(only on proplonged cooling to 193 K)
( slightly at room temp; moderate on cooling to 193 K)
This article goes on to state:
Lithium - doesn't dissolve in dimethylamine but is quite soluble in ethylamine
i mean, wouldn't it be worth a TRY? and so simple. ethylene diamine is totally uncontralled, for one, and wouldn't it be MUCH safer to work with than liquid NH3?
