Views Read Edit View history. Organometallic compounds of the lanthanides. Studies in transition metal chemistry. Whereas n -butyllithium exists both as a hexamer and a tetramer, tert -Butyllithium exists as tetramer with a cubane structure. Crabtree et al. Equally good results are obtained when other cyclomatic derivatives of alkali metals such as l-methyl cyclopentadienyl sodium, 2-isopropyl cyclopentadienyl potassium, l-ethenyl cyclopentadienyl lithium, and the like are reacted with nickel halides such as nickel bromide, nickel chloride and nickel iodide. GHS signal word. Following the addition of Furthermore, the second 8 the ferric chloride, the reaction contents were cooled to about C. In carrying out the process of this invention the reagents can be reacted without the presence of any solvent or diluent. The lithium—carbon bond in tert -butyllithium is highly polarized, having about 40 percent ionic character.
