摘要：

The novel zwitterionic heterocycle 1 was unexpectedly obtained from the reaction between [Li(SiR3)(thf)3] and ArNC. Upon heating 1 underwent an interesting ring opening to give the alkyne 2. Hence the C≡C bond effectively arises from the C-C coupling of two ArNC moieties. R=SiMe3, Ar=2,6-Me2C6H3, tmeda = N,N,N',N'-tetramethylethylenediamine.
