Isopropyllithium diamine adducts: from a non symmetric aggregate to monomeric i-PrLi·(1R,2R)-N,N,N′,N′-tetraethylcyclohexane-1,2-diamine

Abstract

By means of isopropyllithium crystal structures, the transition from dimeric (i-PrLi·TMEDA)2 (4) to monomeric i-PrLi·(R,R)-TECDA (6) via the non-symmetric aggregate [(i-PrLi)3·(TEEDA)2] (5) is shown, depending on the steric demand of the ligand.
