Heck reactions of dichloropyrazine and quinoxaline provided dialkenyl-, 2-alkenyl-3-alkyl and dialkylpyrazines and quinoxalines. Suzuki-Miyaura reactions of the bis(triflate) of 7,8- dihyroxyflavone with arylboronic acids afforded aryl-substituted flavones with excellent site-selectivity. Sonogashira reactions of tetrachloropyrimidine and tetrabromofuran provided di-, tri-, tetra-alkynylated and mixed Sonogashira-Suzuki products with excellent fluorescence properties.
