A series of reusable and tunable polyacrylonitrile fiber supported catalysts that make use of the cooperative interplay between N-heterocyclic carbene (NHC) Au(III) and amino groups have been developed for synthesis of secondary propargylamines. The yield using immobilized NHC-Au(III) as catalyst is twice as much as that of its small molecule counterpart. Moreover, implementation of a flow system...
The l-lysine functionalized polyacrylonitrile fiber (PANLF) was prepared by grafting the l-lysine into a commercially available polyacrylonitrile fiber and showed highly catalytic activity for Knoevenagel condensation reaction. With low temperature (45 °C) and short reaction time (1 h), the fiber catalyst was well applicable to Knoevenagel condensation of a wide range of aldehydes and the yields could...
