Sleeping Beauty awakes: After 102 years of unsuccessful attempts to synthesize azidoacetylene, spectroscopic evidence for this compound has been shown. This highly explosive compound was synthesized by the treatment of ethynyliodonium salts with azide (QN3=n‐C16H33Bu3PN3). Azidoacetylene can be trapped by a cycloaddition reaction to yield a stable triazole, otherwise cleavage to generate cyanocarbene
睡美人醒来:在102年未成功合成叠氮乙炔的尝试之后,该化合物的光谱学证据得到了证明。这种高爆炸性化合物是通过用叠氮化物(QN 3 = n- C 16 H 33 Bu 3 PN 3)处理乙炔碘铵盐而合成的。叠氮乙炔可通过环加成反应捕获,得到稳定的三唑,否则裂解产生氰基卡宾。

Although they decompose rapidly to produce cyanocarbenes, ethynyl azides were generated from (chloroethynyl)arenes and trapped for the first time by 1,3-dipolar cycloaddition at cyclooctyne.
