Synthesis and characterization of para-pyridine linked NHC palladium complexes and their studies for the Heck–Mizoroki coupling reaction†
Abstract
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-CO33 using a more direct treatment of K2CO3 with PdCl2. 3a-CO33 represents the first reported solid structure of a Pd η2-carbonato complex stabilized by an NHC framework. 3a-CO33 can be easily converted to a PdCl2 derivative by treating it with
