最近美国杜邦公司的有机化学家发现了一类新型的有机化合物——全氰烯烃(烯烃中的氢原子全部被氰基取代)。这类化合物的合成并不十分困难。由于它们的结构特殊,因此具有一系列特殊的性质。由全氰烯烃出发可以合成许多新型的染料和可以用做合成药物中间体的杂环化合物,为有机合成开辟了一片新的园地。在这一类化合物中,首先被合成而且经过详细研究的就是全氰乙烯,或者叫做四氰乙烯(TCNE),它的结构如下:
Recently, organic chemists at DuPont in the United States have discovered a new class of organic compounds - all-cyano-olefins (all hydrogen atoms in olefins are replaced by cyano). The synthesis of these compounds is not very difficult. Due to their special structure, they have a series of special properties. Starting from the holoenzene olefins can be synthesized many new dyes and heterocyclic compounds can be used as synthetic drug intermediates for organic synthesis has opened up a new field. Of the compounds of this class, the first to be synthesized and studied in detail is perylene cyanurate, or tetracyanoethylene (TCNE), which has the following structure:
