摘要:
The complexes [eta(6)-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 [eta(6)-arene)-RuCl2](2) with the respective vinyl arsine. The compounds [eta(6)-MeC6H5)RuCl2(Ph2AsCH=CH2)] (1a) and [eta(6)-1,3,5-Me3C6H3)RuCl2(Ph2AsCH=CH2)] (4a) undergo KOBut-promoted intramolecular hydroalkylation in boiling acetonitrile to produce tethered arsinopropylareneruthenium(II) complexes 1c and 4c, respectively. The complexes have been characterized by H-1 and C-13{H-1} NMR spectroscopy, elemental analyses, cyclic voltammetry, and in several cases by X-ray crystallography.
