Synthesis and Structure of Chlororuthenacyclopentatriene

Abstract

The first chlororuthenacyclopentatrienes have been realized by the reactions of RuCl2(PPh3)3 with o-phenyldiyne derivatives in the presence of excess HCl. The structures of the unique chlororuthenacycles were fully characterized by spectroscopic data and X-ray diffraction. In addition, computational studies provided the evidence for their aromatic character, making them as an important supplement to the rare aromatic ruthenacycle family.
