Abstract

The complexes [(η⁶-arene)RuCl₂(R₂AsCH=CH₂)] [arene = MeC₆H₅, R = Ph (1a), R = Cy (1b); p-MeC₆H₄Me, R = Ph (2a), R = Cy (2b); o-MeC₆H₄Me, R = Ph (3a), R = Cy (3b); 1,3,5-Me₃C₆H₃, R = Ph (4a); p-MeC₆H₄CHMe₂, R = Ph (5a), R = Cy (5b); 1,2,4,5-Me₄C₆H₂, R = Ph (6a), R = Cy (6b); C₆Me₆, R = Ph (7a)] have been synthesized by reacting [(η⁶-arene)RuCl₂]₂ with the respective vinyl arsine. The compounds [(η⁶-MeC₆H₅)RuCl₂(Ph₂ AsCH=CH₂)] (1a) and [(η⁶-1,3,5-Me₃C₆H₃)RuCl₂(Ph₂AsCH=CH₂)] (4a) undergo KOBu^t-promoted intramolecular hydroalkylation in boiling acetonitrile to produce tethered arsinopropylareneruthenium(II) complexes 1c and 4c, respectively. The complexes have been characterized by ¹H and ¹³C{¹H} NMR spectroscopy, elemental analyses, cyclic voltammetry, and in several cases by X-ray crystallography.
