Partially fluorinated triazole derivatives were synthesized through anodic fluorination of alkynes having arylthio group and following Cu(I)-catalyzed azide-alkyne cycloaddition (CuAAC) with benzyl azide. The other route toward the fluorinated triazoles, namely the anodic fluorination of triazole derivatives once prepared by advanced CuAAC of the alkyne and azide above was also investigated. It was
通过对具有芳硫基的炔烃进行阳极氟化反应,然后将Cu(I)催化的叠氮化物-炔烃环加成反应(CuAAC)与苄基叠氮化物合成,可以部分合成氟化的三唑衍生物。还研究了另一种氟化三唑的途径,即曾经通过上述炔烃和叠氮化物的高级CuAAC制备的三唑衍生物的阳极氟化。结果表明,这两种途径是合成新的单和二氟甲基三唑衍生物的相互补充的方法。此外,还证明了由氟化炔烃和亚氨酰氯合成Cu(I)催化的异恶唑合成。
