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.
