摘要：

Herein, a highly efficient method for the copper- and solvent-free coupling reaction of acyl chlorides and terminal alkynes catalyzed by 1-phenyl-1,2-propanedione-2-oxime thiosemicarbazone-functionalized polystyrene resin-supported Pd(0) complex is described. Acyl chlorides are easily coupled with terminal alkynes, giving good to high yields in the presence of a low catalyst loading (1 mol% Pd) in Et3N at room temperature under aerobic conditions. After centrifugation, the supported catalyst can be recycled and reused several times with only a slight decrease in activity.
