The palladium-catalyzed three-component coupling (TCC) reaction of cyano compounds, allyl methyl carbonate, and trimethylsilyl azide under a catalytic amount of Pd2(dba)3.CHCl3 (2.5 mol %) and tri(2-furyl)phosphine (10 mol %) gave various kinds of 2-allyltetrazoles in good to excellent yields. A pi-allylpalladium azide complex is proposed as a key intermediate in the TCC reaction.
在催化量的Pd2(dba)3.CHCl3(2.5 mol%)和三(2-呋喃基)膦(10)催化下,氰基化合物,碳酸烯丙酯和三甲基硅烷基叠氮化物的钯催化三组分偶联(TCC)反应摩尔%)以良好至优异的产率得到各种2-烯丙基四唑。有人提出将π-烯丙基铝叠氮化物络合物作为TCC反应中的关键中间体。
