A novel and facile method for direct acetylenic bond formation from the CC double bond by treatment with KOBut in dimethylformamide has been found both in a 9,10-bis(4′-substituted styryl)anthracene series and in a 4-substituted 4′-nitro-stilbene series; its scope and limitations have been examined.
在9,10-双(4′-取代苯乙烯基)蒽系列和4-取代4′-硝基二苯乙烯系列中,发现了一种新颖且简便的方法,即通过在二甲基甲酰胺中用KOBut处理,直接形成乙炔键;其范围和局限性已经过研究。
