The rhodium-catalyzed transannulation of perfluoroalkyl-1,2,3-triazoles with aromatic and aliphatic terminal alkynes under microwave heating conditions afforded perfluoroalkyl-3,4-disubstituted pyrroles (major products) and fluoroalkyl-2,4-disubstituted pyrroles (minor products). The observed selectivities in the case of the reactions with aliphatic alkynes were high.
在微波加热条件下,铑催化全氟烷基-1,2,3-三唑与芳香族和脂肪族末端炔烃的环化反应生成了全氟烷基-3,4-二取代吡咯(主要产物)和氟烷基-2,4-二取代吡咯(次要产物)。在与脂肪族炔烃反应的情况下,观察到的选择性很高。
