Strategies towards the synthesis of palladium(II), rhodium(I) and iridium(I) complexes bearing O-functionalized triazolylidene ligands are reported. Mono-and dimetallic triazolylidene palladium complexes with ether, acetate, and hydroxy functionalities were synthesized using silver transmetalation. Selective formation of either the mono-or dimetallic palladium chlorido complexes was controlled by the amount of NMe 4 Cl used as an auxiliary in the metalation step, as excess halide traps the palladium precursor as unreactive palladate [a]
