Direct C−H Arylation and Alkenylation of 1-Substituted Tetrazoles: Phosphine As Stabilizing Factor
, 2016 Direct arylation and alkenylation of 1-substituted tetrazoles was achieved via Pd catalysis in the presence of CuI and Cs2CO3. Unlike the related reactions of imidazoles and purines, phosphine ligand was necessary to prevent the intermediate tetrazolyl ...
