Title: Synthesis of 1-vinylimidazole and the study of complexation with HAuCl4
Biography: Ani H Hasratyan
It is known from literature that 1-vinylimidazole, when interacting with transition metal chlorides, forms donor-acceptor complexes due to the free pair of electrons of nitrogen atoms in position 3 and the vacant metal orbital. Coordination compounds of gold+3 with 1-vinylimidazole, in contrast to transition metal complexes, are not known in the literature. In this work, we first investigated the interaction of HAuCl4 with 1-vinylimidazole, which, in turn, was synthesized in the NMO/H2O system without the use of explosive acetylene. The X-ray diffraction analysis showed that, in the crystal structure, the AuCl4– poly anions bind to the vinyl imidazole molecules (C5H7N2)+1 by hydrogen bonds of the Cl ••• H–C and Cl ••• Н-N types forming infinite chains alternating in the direction. The vinyl fragment of 1-vinylimidazole is not involved in coordination.
