Dianion aggregates derived from lithiation of N-silyl allylamine.

P G Williard1, M A Jacobson.   

Abstract

[reaction: see text] Three different N-silyl-protected allylamines, i.e., N-TMS, N-TBDMS, and N-TIPS allylamine, were lihtiated by reaction with excess n-butyllithium. Crystallization of the resulting dianions and X-ray structure determination yields three uniquely different aggregates.
