WebJul 21, 2014 · The addition of TMPLi to a mixture of an aromatic or heteroaromatic substrate with a metal salt such as MgCl2, ZnCl2, or CuCN at -78 °C first leads to lithiation of the arene followed by transmetalation with the metal salt to afford functionalized organometallic compounds of Mg, Zn, or Cu.
So far not many structures of Turbo-Hauser bases are known. Generally, they show a complex temperature and concentration dependent behaviour in solution. This is why it is not easy to crystallize Hauser bases and their Turbo variants.
