Polyethylene Glycol Supported Chloro[1,3,5]triazine: A Novel Synthetic Auxiliary for the Liquid-Phase Synthesis of Alkynyl Benzamide Derivatives

Abstract

2,4,6-Trichloro[1,3,5]triazine was loaded on polyethylene glycol 4000 to give a new supported reagent which was employed to carry out the liquid-phase Sonogashira coupling reaction, offering alkynyl benzamide derivatives in high yields under mild conditions by cleavage with amines.
