Lithium compounds with good solubility in organic solvents?

Dmitry Dementiev  Follow

Under inert conditions you may try dissolving pure metallic lithium. Lithium forms naphtalenide salt , I don't see why di-isopropyl-naphthalene should be any different.

Another option would be use of 12-crawn-4, which make a lot of salts lipo-soluble. Presence of TMEDA (tetramethylethilendiamine) should affect solubility of many lithium salts as well, though I would focus on salts like benzoate or perchlorate.

It does react with air and water. However, I beleave, it may be prepared in a sealed vial by careful heating of lithium and a freshly distilled DIPN (beware, some gases may develop). It does not explode, but may self-ignite on air. It is a very strong reducing agent| Yes, it can. But it is a lithium salt with very weak crystal lattice. Though I think, nitrate should work just as well. But none of Li salts are likely to dissolve in DIPN without a helper , like TMEDA or DMEMore

The LS will sit at room temperature. So anything in it needs to be stable at that temperature, including not attacking the fluors (2,5-Diphenyloxazole), wavelength shifter (1,4-bis(5-phenyloxazol-2-yl) benzene) or walls of the container (acryllic).More

How reactive is that naphtalenide salt? Also, I had read that lithium perchlorate is can form explosive mixtures with organic solvents, which would be a big problem in our lab.More

Also, the lithium stearate might be interesting, though with that atom fractions above 1.7% are impossible, but it is worth a look. Assuming it is not so large that when dissolved it acts as a scattering center.More

How reactive is Cyclopentadienyllithium? Would it attack acryllic (what the container walls are made from), 2,5-Diphenyloxazole (fluor), or 1,4-bis(5-phenyloxazol-2-yl) benzene (wavelength shifter)?More
