Reactions of NOX (X =CI, Br, Br3) with cyclopentadienyl complexes of ruthenium

Abstract

η⁵-Cyclopentadienylruthenium (II) complexes [Ru(η⁵-C₅H₅)-(EPh₃)L-L]X or [Ru(η⁵- C₅H₅)X(EPh₃)L] (where E=As, Sb; (L-L) = 2,2'-bipy, 1,10-phen; L = py, γ-Pic, SbPh₃, PPh₃ and X=CI, Br, I, CN, NCS) undergo oxidative addition reactions with NOX (X = Cl^-, Br^-, Br<img src='/image/spc_char/3_bar.gif' border=0>) yielding ruthenium (II) nitrosyl derivatives, wherein NO binds with the metal as NO⁺, a terminal and' linear mode of bonding. All the complexes have been characterized by various physicochemical methods.
