In comparison to beta-diketiminates, a highly exploited class of N,N-chelating ligands, the corresponding beta-thioketoiminates, monothio-substituted analogues, have received only minor attention. beta-Thioketoiminates are straightforwardly prepared through treatment of an appropriate beta-ketoiminate with Lawesson’s reagent. Employing standard synthetic techniques for eta6-arene Ru(II) and Os(II) beta-diketiminate complexes, an analogous series of chlorido-metal complexes supported by different sized N-aryl substituted beta-thioketoiminate ligands is reported. However, metal ligation of a beta-thioketoiminate bearing an electron-withdrawing CF3 group was not possible. The metal-chlorine bond in these complexes is readily activated by various sodium or silver salts of weakly coordinating anions, affording coordinately unsaturated cationic formally 16-electron species. All eta6-C6H6 metal beta-thioketoiminate complexes were characterized by NMR and in the solid state using single crystal X-ray diffraction techniques. Structural studies reveal that incorporation of a thio-group induces substantial bond angle distortion within the metallocycle. The reactivity of the cationic eta6-C6H6 Ru(II) beta-thioketoiminate complexes toward alkynes and isonitriles is analogous to that of the beta-diketiminate species. Specifically, the reaction with 1-hexyne results in a [4 + 2] cycloaddition involving the metal and beta-C sites, while reaction with isonitrile completely displaces the eta6-C6H6 ligand. A comprehensive DFT study employing charge decomposition analysis (CDA) reveals a strong covalent metal-sulfur bond which dominates the metal beta-thioketoiminate interaction. The M-S bond (M = Ru or Os) is strengthened by charge transfer from metal to sulfur, in contrast to the beta-diketiminate species where back electron donation from the metal to the nitrogen centers is negligible. The first reported beta-selenoketoiminate was prepared by reacting a beta-ketoiminate with the Woolins’ reagent. However, this seleno-analog demonstrated significant instability with respect to hydrolysis, and coordination to an eta6-arene Ru(II) or Os(II) moiety proved unsuccessful.
