Use

Lithium diisopropylamide (LDA) is a white pyrophoric powder. Freshly prepared, it is soluble in hydrocarbons (in hexane about 10 %), but it tends to precipitate irreversibly from solution as a polymer on heating or prolonged storage. In ethers the solubility is much higher, but with the exception of tetrahydropyran, LDA is decomposed at a rate depending on the ether, concentration, and temperature.Lithium diisopropylamide can be conveniently prepared from butyllithium and diisopropylamine or purchased as a 2 mol/L (25 %) solution in THF and a mixture of various hydrocarbons. Although LDA is unstable in pure THF (at room temperature a 25% solution loses about 1% of its activity per day), the commercially available compositions containing only a limited amount of THF are satisfactory stable for technical applications.
