General description

Lithium amide (LiNH2) is an amide of an alkali metal with lithium atoms having larger positive charges than hydrogen atoms. It is a moisture-sensitive molecule that converts to LiOH and NH3 on reaction with H2O. LiNH2 is majorly used in hydrogen storage applications.

The syntheses of 2-(di-tert-butylphosphino)-N,N-dimethylaniline (L1, 71%) and 2-(di-1-adamantylphosphino)-N,N-dimethylaniline (L2, 74 %), and their application in Buchwald-Hartwig amination, are reported. In combination with [Pd(allyl)Cl](2) or [Pd(cinnamyl)Cl](2), these structurally simple and air-stable P,N ligands enable the cross-coupling of aryl and heteroaryl chlorides
