Ladder Structure of a Lithium Organyl:  Synthesis and Crystal Structure of a Mixed Aggregate of <i>n</i>-BuLi and an (Aminomethyl)(lithiomethyl)silane

Abstract

A mixture of n -BuLi and the (aminomethyl)(lithiomethyl)silane 3 shows a higher reactivity than the separate compounds. A single-crystal X-ray structure of the mixed aggregate between n -BuLi and the (lithiomethyl)silane ([ 3· n -BuLi ] 2 ) establishes a ladder structure of the lithiumorganyl in the solid state.
