Abstract:
Several pyridinium ylide complexes of transition metals have been reported [1,2] and the change of the structure and reactivity of the ylide upon coordination has posed aninteresting compounds. In this work, Hg(II) transition metal has chosen to study the nature of pyridinium ylides and synthesized some complexes.The ylide used in thisproject is from a 1:1 ratio of salt and K2CO3 in a water solvent for 30 minutes [1]. The new pyridine ylide can act as a ligand that is used in different ways to various intermediates. Reaction of ylide C5H5NCHC(O)C6H5R (R=p-Ph) with HgX2 (X = Cl, Br and I) and Hg(NO3)2 in 1:1 ratio leads to binuclear and polymeric products of the type [HgX2(ylide)]2 and ([Hg(ylide)]NO3)n Respectively. These complexes were synthesized by using methanol as solvent and studied by IR, 1H and 13CNMR spectroscopy techniques [2]. The schematic representation of this complex is shown in (Fig. 1).
