Abstract
The sulfoxide-containing Schiff base (E)-2-((2-(methylsulfinylphenyl)imino) methyl) phenol (HL) was synthesized by aldolamine condensation and oxidation. In the presence of triethylamine, equal amounts of [RuCl2(CO)2]n, [RuHCl(CO)(PPh3)3], cis-[RuCl2(dmso)4] (dmso = dimethylsulfoxide) and [RuCl2(PPh3)3] were reacted with HL to give the ruthenium(II) complexes [RuCl(L)(CO)2] (1), [RuCl(L)(CO)(PPh3)] (2), [RuCl(L)(dmso)2] (3), and [RuCl(L)(PPh3)2] (4), respectively. Compound 4 converted to be [RuCl(L)(PPh3)(CH3CN)] (4′) by recrystallization in acetonitrile. The structures of HL, 1, 2, 3 and 4′ have been confirmed by single crystal X-ray crystallography. In addition, the UV–visible, infrared and fluorescence spectra of HL and its ruthenium complexes 1–4 along with their electrochemical properties were investigated. The catalytic properties of complexes 1–4 for the cyclopropylation of styrene were also presented.
期刊介绍：
Inorganica Chimica Acta is an established international forum for all aspects of advanced Inorganic Chemistry. Original papers of high scientific level and interest are published in the form of Articles and Reviews.
Topics covered include:
• chemistry of the main group elements and the d- and f-block metals, including the synthesis, characterization and reactivity of coordination, organometallic, biomimetic, supramolecular coordination compounds, including associated computational studies;
• synthesis, physico-chemical properties, applications of molecule-based nano-scaled clusters and nanomaterials designed using the principles of coordination chemistry, as well as coordination polymers (CPs), metal-organic frameworks (MOFs), metal-organic polyhedra (MPOs);
• reaction mechanisms and physico-chemical investigations computational studies of metalloenzymes and their models;
• applications of inorganic compounds, metallodrugs and molecule-based materials.
Papers composed primarily of structural reports will typically not be considered for publication.
