Keywords: Sec-butyllithium-monomer-2D-skeletal.png Skeletal formula of monomeric sec-Butyllithium s-BuLi normally adopts a tetrameric structure as a solid in solution and in the gas phase as shown in File Sec-butyllithium-2D-skeletal png This monomeric depiction is not representative of the usual state of aggregation of s-BuLi but is helpful in illustrating the difference between monomeric and oligomeric organolithium structures and is often used to represent s-BuLi when drawing reaction mechanisms Structure drawn in http //www cambridgesoft com/software/ChemBioDraw/ ChemBioDraw Ultra 12 0 Own 2010-09-29 Ben Mills Benjah-bmm27 Images by Ben Mills Sec-butyllithium Monomers |
