Synthesis, structure, and characterization of some ruthenium arene complexes of N-(arylmethylene)-2-(methylthio)anilines and 2-(methylthio)aniline

摘要

A series of cationic, half-sandwich ruthenium complexes with the general formula [(eta(6)-p-cymene)RuCl(MeS-C6H4-2-N=CHAr)][PF6] (3a-h), have been prepared from the reaction of [(eta(6)-p-cymene)RuCl2](2) with various N,S-donor Schiff base ligands derived from 2-(methylthio)aniline and several substituted benzaldehydes. The related aniline complex [(eta(6)-p-cymene)RuCl(MeS-C6H4-2-NH2)][PF6] (4) was synthesized from 2-(methylthio)aniline. All of the ruthenium complexes were characterized by IR, H-1 NMR, and UV/Vis spectroscopies. The molecular structure of complex 4 was determined by X-ray crystallography. (c) 2005 Elsevier B.V.
