Cross coupling of polybromoiodobenzenes with some terminal alkynes
摘要:
Sonogashira reactions of pentabromoiodobenzene and tetrabromo-1,4-diiodobenzene with various terminal alkynes at 20C in benzene resulted in selective replacement of the iodine atoms with formation of the corresponding alk-1-yn-1-yl-substituted polybromobenzenes.
