    Ruthenium Complexes with Vinyl, Styryl, and Vinylpyrenyl Ligands: A Case of Non-Innocence in Organometallic Chemistry

  • Original language description

    We herein describe a systematic account of mononuclear ruthenium vinyl complexes L-{Ru}-CH=CH-R where the phosphine ligands at the (PR'3)2Ru(CO)Cl={Ru} moiety, the coordination number at the metal (L = 4-ethylisonicotinate or a vacant coordination site)and the substituent R (R = nbutyl, phenyl, 1-pyrenyl) have been varied. Structures of the enynyl complex Ru(CO)Cl(PPh3)2(1:2-nBuHC=CHCCnBu), which results from the coupling of the hexenyl ligand of complex 1a with another molecule of 1-hexyne, of the hexenyl complexes (nBuCH=CH)Ru(CO)Cl(PiPr3)2 (1c) and (nBuCH=CH)Ru(CO)Cl(PPh3)2(NC5H4COOEt-4) (1b), and of the pyrenyl complexes (1-Pyr-CH=CH)Ru(CO)Cl(PiPr3)2 (3c) and (1-Pyr-CH=CH)Ru(CO)Cl(PPh3)3 (3a-P) have been established by X-ray crystallography. All vinyl complexes undergo a one-electron oxidation at fairly low potentials and a second oxidation at more positive potentials.

    Rutheniové komplexy s vinylovými, styrylovými a vinylpyrenylovými ligandy: příklad non-innocence v chemii organokovových sloučenin

  • Czech description

    V článku jsou systematicky studovány rutheniové vinylové komplexy L-{Ru}-CH=CH-R, kde byly měněny fosfinové ligandy na (PR´3)2Ru(CO)Cl = {Ru}, koordinační číslo na kovu (L = 4-ethylisonicotinát či prázdné koordinační místo) a substituent R (R = nbutyl, phenyl, 1-pyrenyl). Vlastnosti a elektronová struktura těchto komplexů v různých oxidačních stavech byly zkoumány pomocí spektroskopických metod (IR, UVvis a EPR) a kvantově chemickými výpočty. Bylo zjištěno, že vinylové ligandy silně přispívají k anodickému oxidatičnímu procesu.
