The palladium(0)-catalyzed Heck reactions of brominated benzothiophene provided functionalized
dibenzothiophenes by 6π-electro cyclization reactions. 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.
