Palladium on carbon catalyzed cross-coupling between alk-1-ynes and 2-chloro-4,6-dialkoxy-1,3,5-triazines

摘要

2-(Alk-1'-ynyl)-4,6-dialkoxy-1,3,5-triazines have been synthesized in satisfactory yields by (Pd/C)/PPh3/CuI catalyzed cross-coupling between alk-1-ynes and 2-chloro-4,6-dialkoxy-1,3,5-triazines carried out in the presence of diisopropylethylamine or K2CO3/18-crown-6.
