Luitjes, Hendrikus published the artcileN-Lithio-N,N’,N”,N”-tetramethyldiethylenetriamine and N’-lithio-N,N,N”,N”-tetramethyldiethylenetriamine; oxidative coupling of aminomethyllithium derivatives, Safety of N1,N1,N2-Trimethyl-N2-(2-(methylamino)ethyl)ethane-1,2-diamine, the publication is Synthetic Communications (1994), 24(16), 2257-101, database is CAplus.
N-lithio-N,N’,N”,N”-tetramethyldiethylenetriamine (I) is formed from 2,5,8,11-tetramethyl-2,5,8,11-tetraazadodecane (II) or from 2,5,8,11,14,17-hexamethyl-2,5,8,11,14,17-hexaazaoctadecane (III) with n-BuLi or sec-BuLi, resp., its isomer N’-lithio-N,N,N”,N”,-tetramethyldiethylene-triamine (IV) from tris(2-dimethylaminoethyl)amine (V) with n-BuLi. III results from treatment of N-lithiomethyl-N,N’,N”N”-tetramethyldiethylenetriamine (VI) with 1,2-dibromoethane.
