抄録

The palladium-catalyzed reactions of 4-bromo-and 5-bromothiazoles, as well as 4-bromo-and 5-bromooxazoles with terminal acetylenes gave ethynyl derivatives in 43-89% yields, whereas the reactions of 2-bromothiazoles and iodo-N-methylimidazoles afforded the products in poor yields. The reaction of the halo-1, 3-azoles with terminal olefins was also examined.
