Websec-Butyllithium/TMEDA is a useful combination in organic synthesis where the n-butyl analogue adds to substrate.TMEDA is still capable of forming a metal complex with Li in this case as mentioned above. Other uses. The complexes (TMEDA)Ni(CH 3) 2 and [(TMEDA)Ni(o-tolyl)Cl] illustrate the use of tmeda to stabilize homogeneous catalysts. WebPreparation, structure and reactions. Lithium cyclopentadienide is commercially available as a solution in tetrahydrofuran. It is prepared by treating cyclopentadiene with butyllithium: C 5 H 6 + LiC 4 H 9 → LiC 5 H 5 + C 4 H 10. Because lithium cyclopentadienide is usually handled as a solution, the solvent-free solid is rarely encountered.
