摘要：

Heck reactions of bromoarenes with various olefins catalyzed by 2-iminopyridylpalladium (II) have been investigated. The scope of a coupling reaction has been tested in 1-methyl-2-pyrrolidinone at 140 degrees C using K2CO3 as base. Using 0.1% molar ratio of palladium catalysts, aryl bromides were converted into 1,2-substitutedethene products in good to high yields through coupling with both vinylarenes and alkylolefins. With butyl vinyl ether, an electron-rich olefin, however, the effective coupling reaction produced a mixture of two regio-isomers, 1,2- and 1,1-substitutedethenes.
