This paper describes the synthesis of 1-(pyridine-4-ylmethyl) NHC and their Pd(ii) and Ag(i) complexes, which are fully characterized. Interestingly, we have also synthesized a Pd complex 3a-CO3 using a more direct treatment of K2CO3 with PdCl2. 3a-CO 3 represents the first reported solid structure of a Pd η2-carbonato complex stabilized by an NHC framework. 3a-CO 3 can be easily converted to a PdCl2 derivative by treating it with chloroform. We have found these palladium complexes mediate the Heck-Mizoroki coupling with a low catalyst loading. Furthermore, we also expand such catalytic manifold toward constructing fused polyaromatic substrates, a highly useful class of compounds in optoelectronic chemistry.
