Abstract

The reactions of K[H₂B(bta)₂] (bta = benzotriazol-1-yl) with the coordinatively unsaturated complexes [RuRCl(CO)(PPh₃)₂] {R = C₆H₄Me-4, C(CCPh)CHPh} proceed with loss of a chloride ligand to give the compounds [RuR(CO)-(PPh₃)₂{H₂B(bta)₂}] in high yield. Similar treatment of the complexes [RuHCl(CO)(PPh₃)₃] or [RuH(CO)(NCMe)₂(PPh₃)₂]⁺ leads to the related hydride derivative [RuH(CO)(PPh₃)₂{HB₂(bta)₂}]. The reaction of K[H₂B(bta)₂] with [RhCl(CA)(PPh₃)₂] (A = O, S) gives [Rh{H₂B(bta)₂}(CA)(PPh₃)₂], the carbonyl ligand of [Rh{H₂B(bta)₂}(CO)(PPh₃)₂] being labile and readily replaced by xylyl isonitrile to give the complex [Rh{H₂B(bta)₂}(CNC₆H₃Me₂-2,6)(PPh₃)₂]. Intermediates involving monodentate coordination of the dihydrobis(benzotriazolyl) borate ligand are implicated in some of these reactions.
