摘要：

The hydrovinylation of arylethylenes catalyzed by [Ni(MeCN)(6)][BF4](2)/AIEt(2)Cl/PPh3 was modulated to obtain 3-aryl-1-butenes in high yields and selectivities. A wide variety of arylethylenes containing electron-donating or electron-withdrawing groups and Lewis basic group, can be hydrovinylated at room temperature and under mild conditions by changing the relative ratios of the three-component catalyst. Similar activities and selectivities were observed for o-, m- and p-substituted styrenes. Also, the hydrovinylation of olefins with substituents in the vinyl fragment, such as ol-methylstyrene and indene, can be accomplished. (C) 2000 Elsevier Science Ltd. All rights reserved.
