Reaction of ((2-(dimethylamino)ethyl)methylamino)lithium (<b>4</b>) with benzonitrile gives a new
α-amino
lithium imide, <b>5</b>, which in the solid state is a
tetrameric
cubane. Aggregation is accompanied by chelation of
each metal center using a tertiary amino function,
yielding stable seven-membered rings. The stability
of
<b>5</b> limits cyclotrimerization of the benzonitrile moiety
to
2,4,6-triphenyl-1,3,5-triazine, thereby suggesting a
likely
mechanism for the cyclotrimerization process.
