ABSTRACT:
Lithium diorganoamide compositions are prepared in ethers with an ether to diorganoamide mole ratio of from about 2.0 to about 5.0. These compositions have enough thermal stability generally due to the addition of stabilizers that the decomposition rate for lithium diorganoamide is less than 0.20% per day. Preferred stabilizers are LiBr, LiCl, LiI or Li-tert-butoxide, or combinations thereof. A preferred diorganoamide is lithium diisopropylamide.
