Palladium on Carbon Catalyzed Cross‐Coupling Between Alk‐1‐ynes and 2‐Chloro‐4,6‐dialkoxy‐1,3,5‐triazines.

Abstract 2-(Alk-1′-ynyl)-4,6-dialkoxy-1,3,5-triazines have been synthesized in satisfactory yields by (Pd/C)/PPh 3 /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 K 2 CO 3 /18-crown-6.
